SEO for new business website

I have a brand new website that I need to get SEO done for. The business specializes in a niche bookkeeping industry so looking for experts who have experience with SEO for bookkeeping companies. We want to rank in the top pages for specific keywords. I am expecting you to do the research around the keywords and provide a list.

Must have a demonstrated track record of ranking/SEO for specialized niche websites. If you bid on this project - please use the word accounting on the top so that I know you read the requirements.
