The site looks pretty good in general.
Here are my suggestions/observations;
1) I am guessing that you're trying to sell a service, rather than building a site about yourself and trying to drum up some business while you're at it. (Although I could be mistaken.) If so, I would suggest moving the "About Hatton" and "My Resume" from the top of the list to the space between "Portfolio" and "Contact Me". The service and options you're providing to support that service should be given top billing.
2) The menu takes up a lot of space considering the size of the buttons in that area. It just looks like a lot of wasted space. White space is good, but in this case it is too much. The buttons look a little lost.
3) Maybe for the Portfolio section you could include a thumbnail of the home page you're linking to. Also, those links should open in another browser window. You don't want potential customers leaving your site to see what you're offering.
4) Although the picture of you and your daughter, and associated wording is cute, it's not very business-like. If you're making a business site then make it a professional site and build yourself a separate personal web site for the other stuff. (We're back to my assumption in point #1.)
5) The bottom of the pages look like they just dropped off, particularly the menu column. The buttons looks suspended in space and ready to fall out of the column. Maybe close the columns the same way that they start at the top.
6) There's something about this line in your About page that doesn't come across very well: "Currently I'm looking for work...". It seems to have a bit of a negative connotation to it. You may want to consider rewording that a bit. Something along the lines of "I'm an experienced web developer and hardware technician. In addition to contract work I will consider a permanent position..." or similar phrases.
7) The location of the site name at the top seems pretty much like you just randomly placed it where it is. There's more space above the name than below, it's neither centered or left or right aligned. It also looks a little small for the allotted space. I would suggest trying to enlarge it a little bit, left align it (maybe along the left edge of the buttons) and to center it vertically.
For what it's worth, there's one person's opinion.
