You seem to have a pretty good idea of your own shortcomings — which is a good sign imo, nobody can or should be good at everything — so why not play to your strengths and partner with someone else for the design work?

I've been doing small self-generated projects with 1-2 partners for years. One of them is gaining traction and about to take off in a big way (I hope). I never would have got to this stage on my own.

Note that having a partner isn't the same as selling out, or developing a project with an overmanaged 12-person team, etc. It's pretty much the same as going it alone but with a friend to bounce shit off of.
