In order to get sales, you need traffic of course. I would focus on two channels at first and then look at others. This keeps you more focussed. These channels would be SEO and SEA.

SEO: Start writing about your topic. Both on your own site, a blog and try to get articles on external sites as well (build up the amount of links to your site). Try to include as much relevant terms in your text.

SEA: Start with a small budget, and maybe even one instrument. Set up a dedicated landingpage to point people clicking on the ads to. Keep it focussed on that topic. There are a lot of good articles about landingpage layouts and texts. Try to analyse the traffic coming from SEA and keep optimizing the landingpage and the flow throughout the website to maximize the amount of orders you get from this channel.

Hope this helps!
