PHP Developer

Are you knowledgeable, committed and clever? If you are, and you're also experienced in php, java script and mysql, I have an auction website that uses software from PHP Probid. We've already made several customisations so this person needs to be careful when working on the site. We have ongoing projects so we need someone who is organized, efficient and will ensure the site is totally robust. Occasionally we may call on you for emergency work so applicants would need to be reasonably flexible. Knowledge of website security and SEO is also desirable.
