So speaking with him a little more, his goals aren't that high. He doesn't think he can handle a rate of more than 6 per month, so he isn't looking for volume sales.
He was getting 4-6 orders/month before the recession hit, and was down to about 2 every 6 months. Now he is recovering, and getting orders for about 2-3 every month. He wants to get it back to 4-5/month, and then it actually makes a significant amount of money for his family even after continuing to pay off the loan for his CNC equipment. There was a time back in 2010 he thought he might have to go into bankruptcy and sell the CNC gear. Thank goodness he managed to stay afloat.
One of the reasons he can only do about 6 a month is he supports his family by working full-time as an RN. I don't think he has any current plans to switch to making guitars full time. But if he sees his orders rise to the point where he's losing sales due to long wait times, he might consider making the switch. He's hoping that will be 5 years from now, but maybe more like 10.
It looks like what he wants me to handle first is just writing up press releases, writing copy for advertisements, setting up reviews with guitar magazines and doing the scut work of following up with the magazines and writers to get the reviews published, make sure specs are accurate, etc. The direct sales here in the DC area will be later.
He hasn't said this, but I think his intent is to build his business so it is a little bit more resistant to future recessions, and to make the publicity work not dependent on his energy after working a night shift as an RN, and to stop having to choose between building guitars and spending time talking to people to promote his work. I can understand all those motivations.
Compensation will be marginal for the writing, but you've seen my posts here: I write thousands of words for free, so writing hundreds of words for marginal compensation is okay. Partly because I consider Jon a personal friend, partly because I believe in his product, partly because I'm willing to donate some of my time to help out someone with a vision.
Once he gets up to the 5-6 guitars/month range, I'll get a piece of every guitar sale, in recognition of my help in getting him there. When I sell directly, I'll get a larger cut via a commission.
Final word is he feels like he's made it through the most difficult part of his business life, is ready to start expanding, and is offering me a partnership in the future.
The way I see it is, this is the chance for me to join his company in an official capacity and help him build something lasting. When I retire in a few years, I'll have a good activity to keep me mentally and physically active, that will start returning concrete financial gains at a time when a little extra cash will be welcome. In addition, I will gain no-cost licensing rights to make carbon fiber versions of his guitars, which was something I was mulling over taking up as a post-retirement hobby already.
Okay, with the exception of the last carbon fiber pipe dream that will probably never happen, where are the perilous aspects? Obviously, I need to get the compensation and the expected tasks in writing, with quantitative language. What else? Liability limitation terms?
