Online store based on free open card template

There is a desire to create an online store for the sale of amber. The hosting and domain name is / Text hidden/all the merchandise from the site/Text hidden/---just no time to do-time free (minimum cost). I am interested in the main template, I will add the product myself. The main points - the site is focused on the USA, Canada, Europe, the UAE - payment for the pay-pal (tie my account), - in the product card (as in the source) should be a choice of size or weight of the goods with variable value, depending on the choice of the buyer, - the ability (included and disable function) to order goods with payment for delivery and without. (when choosing delivery, the buyer can see the carrier, a link to its website (tracing delivery by declaration number). If possible, optimize (at least a little) the design itself (a combination of colors, the background of the site), you can offer your own version of a free template. I'm waiting for suggestions.
