Ongoing programming work - Ajax, MySQL and PHP

For my websites I need someone who is an expert in MYSQL and PHP, but who is also able to design and implement changes to the front of the website. You will be working from a sheet with issues and improvements. - This project is on an hourly basis for about 8 hours a week - Payment is only done through paypal and only after receiving a proper invoice - Don't respond if you or your team are not experts - Fluent English is required! - Payment will improve once proven your worth, and once we have made the site ready for the next level. - You will need to clean up the code but also make sure none of the existing features are broken when uploading changes! In your reply I will need you to write a personalized mail instead of all the standard mails I usually get. Standard mails won't be answered, sorry! Looking for long-term programmers
