Sim design experience wanted

I thought I wanted a sim. Actually, I think I only want to design one. I've done a bit of everything since I moved over here from IMVU (where I did mostly texturing,) I love terraforming, and it'd be awesome to try mixing the land textures, I'd really love especially to try mountains. Obviously since I'm not experienced I can't guarantee my work, so I wouldn't charge. I thought maybe there'd be someone who had a sim they'd like designed, if you don't like what I do, then nobody's really lost anything.. but I could gain experience and someone could gain an original custom design for free. I figured it was worth asking if that would interest anybody.. Just IM me about it..
