Constructive criticism here. I am not trying to be nasty (wouldnt take the time to look and write if I didnt care):
There is no flow, no connection between the elements so I am not sure in what order I am supposed to read it. The header navigation does not stand out over the usual text so its hard to see that it is navigation at all.
The icons arent sitting right with my eyes. I think they are too vibrant against the dark background and there are too many of them creating the "minefield" look that Dameize mentioned.
The site is trying to do too much at once and this is killing your "sales funnel".
Think about what are you trying to achieve with the site? Kill anything that doesn't achieve that because it just distracts them from the ultimate goal (which I assume is calling you and booking a callout)
To go down to a page level. I dont think the "Coming Soon" services are necessary. You either do them or you dont. Same with the Custom builds.
There are few spelling mistakes as well:
Front page - Marketing only has 1 T.
Rex Effect - Efficient is incorrect
Custom Machines - i's are not capitalized.
The "
Submit Request" form is asking too much. It asks things like whether the client needs virus support, software support, hardware support etc.. but the thing is that clients wont know what they need. They dont know whether the issue they are having is virus related or hardware related. That is your job to determine where the issue is. I recommend just getting their name, phone number and address for this form.
The site seems to lack consistency. On one page a certain is graphic is a button that goes somewhere, on other pages it doesn't.
I think the biggest improvement would be to give it a solid "background". Not the brushed metal background but the grey it all sits on. Being too modular fragments the flow.
And make the top navigation stand out more, change the color, make it bold or something.
Kill any pages that aren't necessary, too much choice results in no choice.
