Working to Bring More Visitors to Struggling Website

I am a stay at home mother, and it is something that I would not change for anything. Unfortunately, my husband does not make enough money to solely support the family, so I have been making ends meet selling accessories via the Internet. I have a website set up, and although I do make some sales, I really need to get more visitors to the site. My husband actually recommended that I use an seo partner to help make my site more popular. He says his company uses one, and it has really brought them more traffic. I have an appointment set up for next week.
