Hi Jon, Sorry if this is brutal or harsh, not personal at all! Just trying to help.
Code issues
Disability Discrimination Act - Your site fails the disability discrimination act. You could even be sued for this. All business's operating on the internet are lawfully required to comply with this. To comply all your website needs to do is meet the lowest of accessibility standards.
Accessibility - There are many issues with the site in its current state. This ranges from the over use of images to replace text + the lack of alt tags on images to a total absence of hover effects on the majority of links.
Users using a text based browser / audio tools will find it virtually impossible to use your site in its current state.
Wordpress - Great, I use it in the majority of my designs, but why haven't you coded the site yourself? You have some framework on there (sweans?) that seems cumbersome and seems to add far too much code than can be healthy.
Validation - It is always worth making sure your site validates with w3's validator's. This will reduce errors in other browsers, improve your code and generally help your site a lot. Some people ask why don't google validate and this is purely so that they send the minimum amount of data (so the site loads quickly as possible + they use as little bandwidth as possible)
As above with the over-use of h1 tags.
Design
I don't want to comment on the design a lot as my opinion could vastly differ than your potential clients. I also know my design isn't that great so I will keep this brief!
I believe that its overly 2.0, there is too much. Its all fighting for my attention and the end result is nothing gets it. Gradients, shadows, embossing, beveling, buttons, etc all have a place - just not all at once!
However, onto the good! Below the header its fine, especially for your pricing. Its easy to read, nicely contrasted.
General
Pricing - Your pricing is very cheap and thats very fair of you.
The free quote is a great call to action.
Logo - As others have stated, too many colours, stick with 2d, might be worth outsourcing.
