If I were you, I'd start with the basics.

My advice:
Step 1: Follow the threads above and find a niche and gather a set of keywords together for the niche.
Step 2: Pick a good domain name. Something brandable, not spammy. Also, see here for choosing expired domains:

Step 3: Start developing your brand and content. If you need a content writer, I'd recommend
@Geasy service. The price for the number of words you get is perfect for starting a brand new authority site.
Step 4: Build your social media. Facebook, pinterest, instagram, and twitter will help your garner sales. Look into Jarvee for Twitter. There's another bot for Facebook as well. Spam your site to Facebook groups. It works with sales, trust me.
Step 5: Start building backlinks. The first thing you should do is submit your new site to a press release site and hope that'll catch on to other PR websites. Then start building a set of web 2.0 backlinks. There is information on how to do that and also how to index those backlinks here:

Step 6: Keep up with building backlinks and targetting users/sales via social media. Keep pushing and worst case scenario, you can sell the website 6-12 months down the line for a nice profit.
Hope this helps.
