SEO - Top 10 Ranking On Google In US

I have a skin health related website that dates back to 2010 (the exact match domain name dates back to 2000) that used to rank #1 to #3 for my Top 4 terms. These 4 terms have very little competition and 3 of the 4 are searched less than 8,000 times a month in the US on Google. Thus, it should be very easy to rank for these 4 terms. When Google released their latest Panda Update earlier this year, my site disappeared from page one for my top 4 terms and is now ranked somewhere on page 10 :-( I am now ready to hire an SEO expert that can get my site back in the Top 5 on Google in the US for my Top 4 Terms. Please PM me for my URL and 4 terms I want to rank for once again.
