Hi I can provide you with hosting at a great price. Examples can be found here but I am willing to offer TWF forum members lower prices on these.
All my hosting packages including the following FREE:

I have some work to do on the site at the weekend as we have set up a new customer centre so online quick set up won't be online till Monday.
As for advice; Linux servers in the past have been known to perform better BUT advances have been made on Windows servers and the difference between the two is debatable. I use windows servers and have not experienced problems. The reason I use window servers is because I use a different control panel to CPanel. I have had very good feed back on our control panel. You can demo it here:

You can think of web space as a hard drive because that's all it is. Bigger sites need bigger web space. For new companies I would advise starting at the basic packages and paying for more as you need it. Good hosts can upgrade your web space without effecting your site.
Band width is important if you are getting a lot of traffic on a site and you have files like product brochures etc for people to download. Again there is no problem starting on a basic package and working your way up as you reach your limits.
If you are interested in our packages please feel free to PM me and I will offer you a better deal.
All domains can be purchased through ourselves or transfered to us for hosting. Unfortunatly as we are constantly increasing our capacity IP's do change so we do not allow DNS pointing. UK domains can be transfered free of charge. .com / .net domains come with a small charge but this will also give you a longer registration on your domain.
EDIT: Additional Information
*We have many trusted clients and will be in this for the long run.
*Our shopping carts can be installed very easily by you all you need to do is choose a username and password and the rest is done automatically. This also means you can change your mind and install something else or reinstall very easily. If you check out the what's included or the demo control panel you will see the carts available.
