You would need to join an electronics trade website, specific with computing and components, then guard your suppliers you find.
Also if your selling computers register for VAT, although you wont meet the criteria, it will help you buy more products in the initial stages, in the long run it wont make any difference.
Few tips - they are students - get the money or a large deposit then order - saves you having to hold stock, suppliers can deliver usually within 3 days, mostly same day! so you dont need stock, but make a decent enough brochure they can look through.
Good luck.

I recently started University in Portsmouth;
and I've been looking for a job to no avail.
Because of the lack of jobs,I plan to attempt to create my own job, selling to students.
Due to me studying and having a high interest in computers, I believe selling Technology would be the best bet for me to start selling.
Plus I know of many students in my classes ect that are looking to buy Laptops+ Tablets for their lessons.
So, for me to create my business, I'll need to know where can I find a decent Wholesale Technology Distributor that will deliver to Portsmouth, or within a reachable distance?
