Job Description

I am not a MySQL expert at all, and need to write some queries to JOIN various tables and columns etc.

I am looking for an ongoing Skype relationship with someone who can write queries for a simple back-end CRM I am writing in PHP.

You need to understand how to write efficient queries that execute quickly.

I also want to write parts of the site in PDO to make them more secure.
