Can you tell me more about your niche and keywords.How competitive are they?
I can't decide until I know more. What I can tell you about my work is...
-I can place you in the Google News for any keyword you want.(it takes 24h)
-keyword with 50,000searches-on Google No1.page from 1-12 weeks
-keywords with 500k searches -on Google No1.page in 6 months
I would have to see your on page stats.Are you willing to change few thing on the page if I say so?
How old is your business,domain?
Is your site indexed by Google,was it indexed once and now isn't?

Can you tell us little bit more about it?
