Looks professional to me!
Couple opinions:
From my point of view only, I wouldn't put that line at the bottom of the page about "Payment accepted by cash or check" it's kind of off-putting to me. Put it in the fine print, make a point of letting people know when they call for your services that you don't work on credit and you don't accept credit cards. Unless your area is full of deadbeats, no need to put it in neon?
Very minor suggestion, the drop down list of links under the services tag is fine, but if you can on the main services page, put another row under the top menu with buttons for each sub page. I didn't see any links and since Services is your home page, I assumed there weren't any until I accidently moused over the tab. Just a thought.
Well done! :usa
