'I don't want to partner up with the wrong person.' This runs both ways. You need to prove to all your potential cofounders that you're the right person to partner with too. They will want to know that you're qualified and interested Do your ads explain exactly what skills you bring to the startup? Can you show any validation? Have you already found people who would be willing to pay for your idea once it's built? You haven't mentioned exactly what your idea is (and keep in mind it will probably/definitely change as your startup grows) but if it's possible to start finding customers with a solution that requires little or no technology then absolutely do that. In other words, try to find a way to run it yourself. This will either prove your idea has merit, and will make it easier built a team around, or it will let you weed out any gaps in your business model until it does. It's better to find problems before everything is complicated by having two personalities to manage.
