What does '30 days telephone support' mean?
The stupid stock photo guy looks very corporate, therefore not trustworthy. Either get a photo of yourself or just some hardware.
PCwizard4u the name?
I would change that 'special offers' to 'specialist services' and remove the from prices, again very corporate looking. Apple repairs should be relatively easy to quote an actual price (parts price depending of course.)
Change payments to 'We accept following payments'
And less Del boy on the opening, rather than is your pc giving you grief, how about 'Do you need computer support' straight up and to the point. More importantly try not to sound like a sales person, no one likes them.
Like the overall theme but not the white space at the top.
