I agree with you.
I spent about two weeks looking for a designer who worked with both wedding stationery and websites. I found a few that basically did one and dabbled in the other, but didn't find anybody who thought they could do the job. In the interest of launching something to get some feedback, I just did it myself.
Time to start looking again, though. Now that the site is up and I can add users to something functional, I should get back to making it actually look good.
Thanks for the feedback!
