Job: Looking for a PHP Coder

Hi

I'm looking for a PHP coder to do a small job for me.

Basically I need to do the following:

1. Count all of the facebook likes on all the posts on a wordpress site by month
2. Calculate the likes per author (there are two)
3. Create 2 widgets, both showing the number of likes per author and showing if the author with the most likes is in 1st or second place

Anyone here able to do this ? or recommend where to look ?

Thanks

Nik
