There are several different things that you need to look at before you decide on which web host to use
. The amount that it will cost you is one of them. That is not the most important though. If it was then there are plenty of really cheap or even free hosts that you can use. Listed are other things that are much more important to get from your web host service.
Any one that will have lots of pictures will need much more space than a free host will have to offer. Space is something that can't be negotiated. Either they have it or not. If you have product that you want people to see to possibly buy, then not having the space to show them will make that impossible.
Up Time issues. Although most web hosting services will offer you at least 99% up time, there are still a few out there offering less than that. Don't settle for a hosting service that doesn't at least offer 99% up time. In the current format, if they are a reliable company they should offer at least that as part of their package.
To make your site the way that you have imagined, you will need some good tools to do it right. This can be an easy process, or something confusing. That is why you will need to see the collection of tools that they have. Therefore you want to get a host that will let you use their tools for free, and make sure it isn't too complicated either.
Everyone needs a little assistance sometimes and having someone in customer service available at these times is crucial. This will make a big difference in your experience with your web host. The free and really cheap services are not usually into having people on staff to help with this, so check that before you go with a host.
