I get many unique users to my website somewhere in the range of 200-300 a month but I am not turning them into buyers...there is a reason they are leaving...
It sounds like you are assuming that your site has an unreasonably low conversion rate (# of orders / # of visitors). Are you sure of that? As far as I can see, your current site looks similar to other TF sites, so I believe that your current conversion rate is also similar to theirs.
If your conversion rate is similar to any other TF site, there may not be much you can do to dramatically improve the rate. Small, incremental changes you are talking about may improve the rate a little, but not dramatically like >2 fold.
If I were you, I would focus on improving the number of traffic. "200-300 visitors a month" sounds too low to me.
