Ask HN: Single founder seeks SEO/promoter for revenue share

I'm on the lookout for a SEO/promoter interested in a revenue-share agreement. I have approached a couple with this idea but most seem to think I'll disappear once the results start coming or that they could build a site themselves. On my end, knowing who is worth the time in the first place is a challenge.

The site is a non-trivial application in the travel industry and is well-liked by almost everyone I've shown it to. It's been in the press a few times and had a bunch of resulting sales, but I don't have the time to continually promote it -- I'm a one man operation and I need to focus on other things, like actually working on the site itself. I'd like to take a hands-off approach to promotion and I have no problem sharing revenues and signing contracts if it gets me somewhere.

There's no way I am in a unique situation here -- most single founders have probably been in the same position. Any recommendations?
