Hi, my name is Kyle, I've ranked a site in 2 months on page 1 in Google in a VERY competitive niche locally. There are many agencies or companies that you can hire for online marketing. Some are better than others, and some are terrible and may hurt your site. Some larger companies hire in house online marketers to provide on-going marketing. It's always best to consult with a few professionals or 'SEO's' before making a decision on who you go with or how you go about your marketing.
