Someone wants to buy one of the themes on my site but I want to continue using it. What's an example contract or agreement that I can give them when selling the theme so that I can continue using it on my site? I designed all the themes on my site. I don't offer any of them for sale although I've sold variations of them when people have asked. This is just another one of those cases where someone asked and even told me what they'd pay for it. Normally I just tell them here's my paypal and shoot them the theme after I get the money but I haven't been asked to sell something for that much before.
