Complete SEO for blog

I started a blog 5 mths ago : http://coolquirks.com. I know it's not easy but I aim to create a site like that of [login to view URL] or coolmaterial.com. Focusing on the niche of cool gadgets and accesories for men as well as the other interesting tech news. I've been reading up on SEO by going on forums like warrior forum and also studying books about it. More importantly, creating blogposts everday. But with 200 plus hits a day, the site isn't going to get any affiliate sales or ads.. Currently, im targetting the keywords Cool Gifts for men #68(current position) Cool Gadgets for men #10 Cool Gadgets for guys #20 Cool Stuff to buy online #14 Cool stuff to buy Best gifts for men gift ideas for boyfriend Could you advise me on whether this is going to be profitable? or any other keywords which are good to target as well? How much would it cost to rank 5 of these keywords within the #1-#5 on google?
