Well my earlier advise still stands..for starters fix your keyword density..
It's still an excellent market (PDAs)..you have a nice site ..
I know it's it's frustating but just take a few months and re-build your traffic..
Let me ask you this..are you familiar with Googles PR ranking system? and if so when you first signed up for homestead was your PR a 6 then also ?
If so we may have stumbled on a nice little kicker and you may be best off paying $200 a year..$17 bucks a month isnt much if you can feed off of the homestead PR ranking from google .if that makes any sense to you..
It is difficult to get a site to a PR 6 , 7, 8 ..their are only literally a handful of INDIVIDUALS with a PR 8 ...
I hate dmoz..but try and get your site in their listings also ...DMOZ feeds so many engines it can be very important..
also for $39 ..this is a must http://ink.ineedhits.com/
the thing thats important about it is your sites refreashed every 48 hours ..so if your ranking is low it lets you tweak your keywords until you find the right density and combinations to move you up....you just have to wait a few days instead of months...
