SEO and marketing improvement required for small single product website

I have a small website selling a patent pending guitar music holder worldwide. Currently sales are low and it is difficult to find the site via google etc. I need to increase the traffic to my website to increase sales. I am also interested in other marketing techniques that will improve sales. Currently the site is getting less than 50 hits per day. I am looking for a one off optimisation and site/marketing review with a view to further products being added in the future. Searching for \"Pocket music stand\" on google will bring up the HandyTab site. Estimate of hours and rate required for quotation.
