Hi, if you are happy with an American company, I recommended VodaHost (click here) I have used them for a few years now. Excellent Customer service, Nice people to deal with, Excellent services e.t.c.
In response to you wanting to build a shop,
-They have free website building software (click here) This a good software for the beginner-intermediate user.
-They also have an on line website builder (This is is has ecommerce features) (click here)
Although I only use the first (Blue Voda) I do know for a fact that they are both very powerful, and i should think they will have everything you will need. I would personally recommend using Vodahost's Soholaunch.
Both of the links above go to a page, with a quick demo explaining what they offer.
I hope this makes some sense and is of some help to you.
