Welcome to the Q&A Forum

I think you should be focusing Local SEO. Get your business listed in Google maps, Yahoo local and Bing Local directories. Try to encourage your customers leave a positive reviews there. And of course, you can run PPC campaign in your locality that would not cost you huge. Get your business listed in Yellow Pages, Yelp etc and you can get some good leads, apart from a link back to your website. You can approach local communities, newspaper to get your article or advertisement published there. In case of advertisement, do not forget to add – rel=”nofollow” against the link. Hope that helps
