Designing your own site is really not the best way to go about it, especially if you plan on selling items using a secure transaction method. Unless you`re extremely into the technical side of the web, and very good at the visual side, you will find the task to be overwhelming.I suggest you find a good, reliable, designer and back end programmer. I know there are some hanging out on SuN, as well as many across the country. It`s really not necessary to hire people from your own city in this situation. Just do your homework and truly investigate the candidates you feel will work well.
