Been there myself, and to add some insight on it, I didn't bow down and kiss ass, lost the job due to the fact the owner didn't believe me, either way, I was out, even though the work was good. It can go either way for you, I'll agree with about everyone here on advice, once you go down the road of "being bought" your labeled for life and it'll cost you more in the end, when word gets out, your scamming the paying customer, your done for in business.
I lost out on a lot of work over the deal, but after some time, its come back around, I now do work for some others, that heard what happened and how it went down, that did believe me. I'm now the only one they call, and it makes no difference who or what's involved, they trust me to be fair and honest with them, that and nobody ever tried it twice, I've been told I can't be bought off so those types don't even try anymore.
Best of luck on however you decide to handle it.
