Website with Shop

We have signed up with 1 & 1 to do a simple shop for 2 downloadable books with pages of adverts. We would like someone to just do it for us, it needs to be done pretty quickly. We would probably prefer someone who can do it through 1 & 1 rather than messing with getting it away from them but it's rather more important to get it done and get it up to start selling. We need someone with time who can do a good job with someone which will be online for 6 -9 months.
