If you have 2 companies interested, I'd tell them both that you have other companies interested, make me an offer. Edit: as a rock-bottom baseline, try to figure out how much time and money you've spent on this and use a rate like $150-200/hr to get a bottom number, assuming you'd have no further involvement. If they want you to commit to future involvement, it's more of course.
