There are a lot of good thoughts here. I think Hamish has a lot of great points that I would agree with. If you're just selling one or two and not making a habit of it I think you can get away with doing whatever feels comfortable for you and the other party.
Pricing self bows is a funny thing. There are people with weird ideas about selling self bows. They get some purist ideas about what should and shouldn't be done. I don't really get it. You don't see these attitudes with other types of crafts like bladesmithing or furniture making. No one gives people a hard time for selling these things at a price to make a living. Like Pearl Drums said, if you make good bows then don't worry about selling them.
When I price my bows Here are the things I have to consider... The true value of the wood (not necessarily what it cost me, but what it's worth if I sold it), the time it's going to take me to make it from start to finish, including extra stuff like recurves, skins, overlays, etc. ( what's your time really worth? don't give it away. Your expertise is worth something. You're not flipping burgers), I have to account for an occasional failed stave or aborted project, I have to pay an 11% federal excise tax on every bow I sell on top of my regular income taxes (that adds up fast over the course of a year), as a business I have to take into account all of the ancillary activity that I do that I'm not getting paid for (cutting staves, paperwork, errands, etc.) There are probably more things that I'm not thinking of off hand but you get the idea. I charge a high price for my bows and I'm not ashamed. I've spent years refining my craft (and I continue to do so). People value what they spend their hard earned money on and I'm not getting rich doing this. I can't control the fact that some people are willing to do highly skilled work for peanuts. I just focus on making the best bows I possibly can and I'm grateful that enough people recognize the hard work and expertise that goes into that they are willing to pay what I ask for them.
