If you don't want to do someone else's project, what do you have to offer that they would want to do yours? I'd reconsider that stance. If I were you and the keyboard player, I'd go out and do whatever projects you can to go out and meet other musicians and get them interested in working on your project, too. You have to give musicians an incentive for doing it, either monetary or the offer to help them do their separate things in return for doing yours.
+1 My thoughts exactly. This to me shows your lack of experience. A lot of great players are simply not going to commit solely to your startup original electronic music project, and you are shooting yourself in the foot with this attitude.
In fact, I would go so far as to say you need another project or two yourself to take the pressure of this project. Get in a cover band, go get that performance experience, network with other musicians on the gig, with club owners, with the music crowd in your town. You might be coming off as a bit needy right now since you've got all your eggs in this one basket.
