jamieludlow,
Typically, I do not like going with the flow of forums and the "older" individuals of the hosting industry; however, Blue and Artashes is right. This "project" that you are undertaken is way over year head.
Think about this, Blue, Artashes, and myself all have built successful businesses. It took several years of research, operations, and marketing to get to the point that we are at.
You project $45,000.00 euros in the first year. Sorry buddy, but the web hosting industry is not supportive of that for new firms. To gain $45,000.00 euros it would take 1,800 clients on a $24.95/month plan. Most individuals enjoy sitting ont he $0.99 - $9.95/month plans.
I am 19 I have been running BHN for going on 15 months now. I have a college degree already and there are some days that I have my accountant and lawyer in the same room with be for hours.
Keep your head up, research more indepth, develop a business plan, and work as a Level 1 or 2 tech for awhile. For the most part, companies will hirer techs in the range of 16 to 24 for Level 1.
