Take this FWIW, of course
That home page is a bit too busy, for my taste. The purpose of a home page should be to introduce your company, not throw everything out there. That can easily be split up a few ways.
The slider is nice, but on the homepage, rather dominant. At 1920*1080, it's pretty dominant, like taking up just over 1/2 the screen, on a 27" screen . On a 22" monitor, it's way more (more like 3/4).
Dropdown menu at the top? Same thing. Condense it .
The text looks pretty decent, but , again, too much of it on the first page. This is something that will turn clients off.
