Only $50 to Spend on Affiliate Marketing Fast Track

Ok, I have been learning and acting on numerous online marketing activities for years now. I have dabbled in affiliate marketing, set up adsense sites but got bored with backlinking, have 3 books selling on Kindle....I have a hosting account, Market Samurai, can set up a WordPress site,have set up successful adwords campaigns, ...I am weak in a lot of other areas but I suppose I know a lot more than your average Joe.

I realize I need to focus on one aspect and go for it. I have decided that if I had focused on affiliate marketing years ago and not bought into the new shiny I might be successful today. So here is my question....

I have about $50 I am willing to spend one last time to fast track my learning curve with affiliate marketing. I want to build an online business desperately. I will devote 20 hours per week now and more later as things progress. Can anyone recommend a good solid tutorial on affiliate marketing that will guide me (after keyword research, domain reg, hosting, WP set up, etc)toward success? I don't want a $500 or $2497 program (already wasted a huge amount years ago with Michael Cheney's overpriced Golden Thread>>>arghh)

Everything I look at gives me that same sense of...oh crap...this is just another carrot leading to an upsell. Somehow I know that there is someone out there that will really teach affiliate marketing without charging through the roof....am I nuts or is it out there. Tell me please....I read Tiffany Dow and Lynn Terry's blogs and they seem genuine but I am gun shy at this point....thanks for any opinions. I feel certain a lot of other people would like some recommendations as well.....

I am dedicated, determined and will take action.....
