The only relationship better than those built on love are those based on cash. So you need to make sure that your parter is well compensated. And you both have a well defined exit strategy.
I've always found that partnerships work best if there's a clearly defined ownership of duties. You do this, they do that, and you aren't the boss 'o them in their job. In other words, partners are 50-50 in terms of sharing tasks; they're 50-50 in terms of assigning indivual tasks, then you own 100% of your half of the tasks. If they do marketing, they do marketing and keep your beak out of it :).
The initial problem is that you are starting with 100% of nothing and they're going to build it so that you both have 50-50 of something. I don't know that there's a best way to build someone's ownership from 0 to something. In fact, I've run into this before.
I was offered a substantial portion of ownership for doing SEO on a project. I didn't have time for a maybe, so I declined. They built the traffic, then called me back to ask about the SEO again. At that point I said 'sure, but how bout a cut', and at that point they declined - because now they had a gtd. traffic base.
