Losing my Mind: Needed - vendor script for variations of item

I'm about to lose my mind... no wait, scratch that, I have lost my mind trying to find a vendor script that fits the following criteria:

+ The vendor script is to be placed inside an object (let's call it Thingamabob).

+ When touched, a menu pops up with the following options:
Thingamabob version A L$100
Thingamabob version B L$200
Purchaser can choose from one of the versions and pay that amount, and receive the appropriate object.

+ Monies received can be diverted to another avatar (someone other than the owner of the script and object).

I know these exist, and I've found "script" places in world, but I'm reluctant to pay for something when I'm uncertain if it's someone selling a freebie or if the script can even do what i purports.

Help, please and thank you.

Nothing complicate in here... Well, depending on how configurable you want this thing to be.

Meet me in world, I already have plenty of ideas about how it could be made.
