You need to remove from the visits figure all visits which are not from potential buyers. This includes automated visits by search engine spiders, visits by you, visits by all your mates who you have told to go and admire your new site and visits by things like AOL proxies (1 person on AOL could be clocking 20 visits because of their weird system).
It is quite possible that by the time you have removed all these you will be down to a few hundred visits.
What percentage conversion rate are you expecting?
What percentage conversion rate are you aiming for?
You need to benchmark the site, so that you can evaluate the effect the (valuable) changes which have been suggested to you have on the conversion rate, you may find that some of the (IMHO very sound) suggested "improvements" to the site actually hurt your sales!
Once you know how many visitors you need to get to make a sale this will enable you to evaluate whether SEO or advertising is cost effective for you. There is no point having superb traffic delivered by a keyphrase (SEO or targetted ads) if none of the visitors brought by it ever buy from you and you need to know how much you can afford to spend.

By the way, your product is
style - you need a site which matches that. It might be worth your while to get smeone like Eagle to do you some graphics or even just a logo - his work is awesome - and then get them implemented into html by an expert.
