( sorry quoting 80s dance track lyrics ...see if you can guess them?

anyhoo onto more serious questions.
Ok..Ive been approached or rather ive responded to an advert for the sale of an in world business ( and items ) Now I must stress I have yet to master the skill of creating squat in PS7 and i am at the earlt stages of tutorials..I know my way around it but still learning alpha channels etc..so anyway i add this as the store/items are made in photoshop and I cannot rely on the sellers older items to keep me a SL living without me introducing new stuff.
So the sale was agreed...all his/her items templates, textures, bundles in the store at the moment all out on display, I have seen the sales info of lindens sold to 3rd party linden buyers and over 5K have been sold since July 2004.
And I have seen the account history info also showing regular sales but it doesnt say what item so I guess ill have to trust the person that the items sold are indeed the same as teh ones I am thinking of buying.
I have been offered full rights to the in world textures, bundles and primmed stuff..and the original templates for PS7 so I can play about with them...learn from them etc.
Anyway. asking price was 1300USD . They arent playing SL anymore...started a RL business and wont have the time to devote to it. The store was on teh bottom of the list regards to that particular product type but i was told when they released new tproducts the traffic went sky high. ( of course... I wont be for a while so I had to look at it worse case scenario ) they have some items they havent released into the store yet but wouldnt let me have them???? Said I could buy them ontop of the agreed sale amount after Id seen them I could buy them individualy for 10USD each
I offered 1000USD for the lot in the store with full rights and all the original PS templates too.
Was refused originaly...then agreed soon after.
I dont have much money and I dont have any brilliant skills either yet...working on them but as you know its a massive time commitment to learn PS ...and the items in question altho nice I feel are starting to be outdated and replaced with more upto date versions.
I wish I could go into it more but I dont want to offend the person in question...this is their talent and no doubt her pride & joy.
anyway...question is this.
Has ANY-ONE got any experience is this kinda thing?
I dont understand why they cant just get on with their RL and just rely on the sales of their stock as it is?
I own a texture store and know they will continue to sell regardless of me being there...I even asked them this question but got no reply.
I am a very skeptical person by my very nature.
I am feeling until and assuming I can create something that resembles the products they have made..I will be relying on the sales of their old stock...but at the same time...i would give ANYTHING to get my hands on some PS templates for hair so I can see how ppl make them..what tools they use...i know alpha channels are important...God im so frustrated...I just want a little piece of pride

So my desire is to learn from their work..modify it...copy it...play with it..market it better...( they only had it out in 1 store I would have them in vendors all over SL ) and hopefuly pick up where they left off in time but 1000 USD is such a lot of money.
So the question is both moral and technical.
Should I concentrate on building my own success? If so is ther any-one kind enough to donate some old and unwanted PS templates on hair for me to play around with? Just so I can see what colors...brushes...how many layers...etc?
Or is this infact common place? Do lots of people sell/buy in world business for this kinda money? Ive heard of land being sold..
The person in question may be just dumping her old stock and then creating a new account and starting a new store with her upto date stuff for all I know?
What would you do guys? In my shoes? I work from home part time...2 hours a day telesales as I suffer M.E and I dont have much ££££ but I could stretch to this...is it wrong to buy others skills & talents? even if its to learn from etc?
All I would want is to ensure I got my money back and to make the business grow but after looking at the latest hair styles out I feel the stuff I would be buying is sorta being replaced now..primmed curly hair etc...I am no fashion dictator in SL...not up with the 'ins & outs' but having just seen Lost Therians latest hair style I kinda cringed and thought ' what am i doing??? I cannot compete with that!'

Im confused...i was turned down and i put it to bed...then they wrote this morning saying ' ok ill take the 1K USD for the rights to everything in the store' and now I am not so sure I want it.
Question is.. is this normal practice..is the price reasonable...am I being insane? lol
Thanks in advance for reading my ramblings
