Currently i have a free website and a eccomerce shop that i think is 60 quid a year. I have 5 domains linked to sites.

Im thinking of paying out for a proper site doin that will rank high in google etc to make the eccomerce side earn me money rather than do a sale here and sale there.

1st question is, i like my eccomerce site and know how to use it etc, can i just get a website made then get the shop linked so the site will get the hits and i can carry on with the shop as is?

How much would i be looking at for say a 3 page site with link to my shop?
