I have an old OC that I don't use anymore due to lack of interest and connection with it. It was made a long time ago when I wasn't really happy with myself and I kind of want to get rid of it now...

Question is, I've never dealt with these kind of 'transactions' before and I'm not even sure how to proceed with it! I have a reference sheet along with a few other pieces of art containing this OC which might equate at about 900$ USD, but I don't even know what kind of pricing I can apply... Obviously, the amount requested would be nowhere near how much I've put into him, but what I would be selling is the rights to take the character and pictures and make them theirs.

This is all hypothetical, but I just wanted to confirm with the rest of the community if this is the sort of things that are accepted/done often around here and, if that is the case, if anyone would be interested.

Please let me know for I have a few projects in mind, but lack the funds to start them and being able to sell my old OC would be a huge help :P

(Also sorry for how confusing this message is, I don't even know EXACTLY how I would go about this yet...)
