Even better, get a designer as a co-founder. Specially for startups bootstrapping.
Really good designers are hard to find/likely already occupied or juggling multiple projects at a time. IMHO, design is a never ending process.
You'll hire a good designer if you get lucky at your early days but then retaining them becomes exceptionally hard. I've found that having them onboard as a co-founder seems to be the best way to work through this.
