ArtMetal

I've never had someone ask to lease my stuff(they just ask if I'll do it for free), but it sounds like a way to get good art without paying what it's worth. If the pieces are already made and taking up space, it might be a good way to get some exposure and $, but I don't think I would design and create something from scratch. Just make sure you get paid for your work, in reality when you lease something you usually pay more than if you bought it outright(for the time you possess the item). Let us know what the agreement is like.
