From a tech perspectives, it seem good, nothing wrong since I would craft it out the same way too last time when I'm starting out. I will be a bit blunt here, in the hope it will help you to get more conversion. These feedback are mostly from the point of marketing and sales focus - with the aim goal of getting enquiries and hopefully business instead of just informing people what we do.
Too many words, no pictures - business owners like as few words and as much pictures as possible. You need to grab their attention.
Strong attention on features of what you do, no clear showing of benefit/risk from clients' POV (they are hidden within the wall of text). - By writing it the way it is on your first page, it attracts enquiries from peoples who already are on the lookout for IT support and the stuff you listed. What you want is to grab the attention of people who are not thinking of getting IT support by showing them what they are missing out on if they don't engage you. Those looking for IT support will naturally enquiry on your services when they see the pdf, whichever way you present it.
Information on backpage is redundant with the way they are presented. As in they will read it as "we are yada yada good, we yada yada better..."
If you want to showcase your outstanding areas, put it in the form of a story. It will resonate better with them rather than coming across as blowing your own trumpet.
Try adding a testimonial on each page or the backpage, it will help greatly.
