Your trying to target a keyword with 182,000,000 results, it really isn't going to be very easy to rank highly in it. It all depends about how you promote keywords, I suggest you start trying to rank highly for less-searched terms, you can rank for these keywords from using link wheels and other methods similar to that, once you've built up a lot of small-traffic keywords, you should be getting a nice flow of traffic from Google, then you can start thinking about ranking for these much higher-traffic keywords. That's just my advice, it's better for your website/blog along with the fact your not going to spend months of time trying to rank for one keyword, when you could build 5 link wheels a day, rank for 5 new keywords each day and the traffic does really add up.
