UK PHP/MYSQL Developer to support ongoing site development

I have a full project and content management system built in PHP and MYSQL over the last five years.

Just recently we have added some interaction with a number of external API\'s. Some of these require frequent changes, so I am looking for a UK based developer that can provide 5 to 10 hours of dedicated development each week.

You should be accessible by email and telephone - and should be prepared to react quickly to issues that arise.

You should have very good PHP, MYSQL, Ajax, CSS skills - and a working knowledge of XML and API\'s. Occasionally data is acquired through regex matches of API output. None of this should be new to you if you submit a bid. I am not looking to train someone up - I already outsource all main development overseas.

Initial bid should be for 20 hours in February.
