Nice, these are great tips. I do part time web design. I take on small projects that interest me for the most part. If a project is over my level of knowledge I just come out and tell the customer I can't do it and sometimes point them to a designer that can. I've seen so many web designers take on mega projects and they have no clue what they are doing, then just close up shop and re-open under a new name. I can't believe the amount of times I see people buy terrible sites, with all kinds of bugs and glitches too. It's great having a site with all the bells and whistles, but if it's buggy and things don't work you'll lose more customers than you gain.
