Hi qwerty.
Your website appears clean and usable. However, there are some clear issues to look at. As said already the text size is too small.
The menu is confusing with far too many links being shown. You should only include the necessary main links in this main menu and have the rest in a bottom or side 'submenu'. For the main menu I would go with: home, services, portfolio, about us, request a quote. Nobody includes a sitemap link in the their main menu. Think what you want your visitors to do, and what they will want to do. It will probably be: see your work, learn more about you, or order a design, so anything that doesn't cater for these needs should not be given equal important in your navigation. Try reducing menu links also through the use of subpages or merging content to a single page (services/about us could probably be combined).
The swoosh shape in your header is very 90s, I would go for something more modern to show off your talents as a designer.
The search form at the top of the site is in an awful positiion, nobody generally is used to seeing a search form there, and more importantly it pushes down your whole layout, including important content. Less scrolling is better remember. So I would scrap the search altogether, after all you are a small website. Then move the layout up so the header touches the top of the browser.
Get rid of the paypal donation button, it looks unprofessional and desperate.
Give the side column content boxes headings ('featured design') etc as you can't easily work out what they are.
Oh and your logo is confusing, it could be 'phase design 32' 'phase 32 design' who knows... so I would scrap the word design as its quite obvious what you do, and your logo would look a lot nicer being simpler.
Hope this helps
