The reason I'm asking is because I'm working on a site and I just don't believe that I have an eye for what looks good. I know what good code looks like though. :)
Definitely worthwhile to get a designer in, if only for the basic branding elements; logo, type, palette.<p>Spend some time on designer hangouts, like dribbble, find some designers you like and ask for some quotes. In my experience it's always better than what an 'amateur' comes up with and surprisingly affordable.
we currently do interaction design / wireframes ourselves and plan to get a visual/graphic designer onboard in the next weeks.<p>one point learned already here: a visual designer could have given valuable input early on. so try to gather some ideas from designers early on
