Web Site Design

I currently have an ebay featured shop in which I sell primarily plus size lingerie along with general lingerie & jewellery. Although quite successful the fees & charges made by ebay reduce any profits to virtually nil. I feel the way forward is to have my own online store. I would like a fairly standard professional looking website, personalised to my products. I would need approx. eight to ten product categories in which to list the different types of lingerie & jewellery. For example 'Sleepwear / Nightwear' 'Basques''Bras' 'Briefs & Knickers' etc The number of items I have listed on ebay at present amount to about 85. These could be reduced if I was able to give choice of colour & size. I cannot do this on ebay satisfactorily so each individual item has to be listed as one. Standard features would include a logo, basket / checkout, info, home page...all the usual things! I have all the relevant photos for all my stock and use [login to view URL] for picture hosting. I use paypal as a payment source and am considering using nochex. I would want to be able to accept credit / debit cards. I regularly update stock & prices hence I need a system which would enable me to do this myself. I expect there are other features that I have omitted which I should include, however, I would expect an experienced designer to include any extras that a normal online store would expect to have.
