Hello,
I can do a SEO of your web site to make it rank higher on google.com. That way, free of any charge, you will be able to draw more customers that are already googling for terms that describe your business. Depending on your current SEO ranking, it will take some time to reach high place. In the meantime I would suggest Google Adwords, to promote your site, again, only to those who really google for something you are offering.
Please contact me via chat do discuss more.
Regards,
Vladimir
