Should I focus on finding good affiliate programs and promoting them from my site?

Question - Should I focus on finding good affiliate programs and promoting them from my new site, in particular the Solo Build It one?

Answer - Affiliate programs are a great way to get started and the Sitesell 5 Pillar Program is one of the best...however, selling Solo Build It and other sitesell products is very difficult because there is a huge amount of competition and it's not a very big market really. 

If you would like to join and give it a go, by all means, but I'd tackle a market in which you could quickly become known as an expert (even if it was just locally in your home town or state initially) so you can carve out your own niche doing something that interests you and you know a lot about.
