okay.
1 - There is no such thing as unlimited hosting. The ammount of time I have seen people fall into this trap - I'll give you unlimited hosting for such and such a price. By the next week, their (normally reseller, not VPS or Dedi) is maxed out, with very unhappy customers. People offering unlimited services oversell, and that's the truth of it.
If you want to offer a similar thing to unlimited, you would specify that it is unmetered, and would include an acceptable use policy.
2 - £70 is a lot of money for free software and about an hour re-branding and changing some images on photoshop. When I used to offer this service I only charged £11 because it was nly worth that.
Reduce your price or no-one will buy.
3 - Can you guarantee 5 years hosting? The only way I can see if this is truly legit is if your vps/dedi etc is paid for 5 years, with no chance of the provider dieing either.
