Bug fixer, server review & PHP Coder Required for Ongoing Work

I am looking for someone on an ongoing basis to help with a rather complex woocomerce build on the technical side of things.

This is for an experianced UK based freelancer only who is used to dealing with errors, server management, database optimisation, email delivery, bug fixing, php code writing and editing on woocomerce developments.

I have a current error that needs looking into asap that I can discuss in a more private setting.
I need to work with the programmer directly so please no agencies and this is advanced level work so experiance in this is a must.
