Whether you decide to actually sell it or not, I would recommend asking this person what is that "reasonable amount" that they are willing to offer ? They contacted you which means they are more interested in buying it than you are in selling it at the moment. So even before you get to the point of valuing your code, just ask them "what are you willing to pay" ? If they ask you back "what will you sell it for", you tell them "I am not really looking to sell but willing to hear your offer and I might consider it depending on what you offer". Don't give them anything more than that. Remember that "reasonable" is very subjective. When it comes to buying/selling/negotiating, don't work with subjective stuff. Ask for specifics. If they don't want to specify, then they are wasting your time. Put pressure on them to come up with a number first.
Again, they want to buy it rather than you wanting to sell it. Big difference. Make them do the dirty work. Let them talk more. Let them give you a number. Until then, sit back, relax.
If they do come back with a number, then you have a different set of things to think about. For now, let's not worry about that.
Thanks, that's a good place to start. Coming up with a number out of nowhere was stressing me out, but if he initiated the discussion I'm sure he has something in mind.
