PHP site editing, updating

We have a PHP site up and running for a small clothing store in Denmark. The site was built using a template and runs on a Unix server. The site is in English and Danish. We need someone with extensive PHP/MySQL knowledge to help answer questions, edit buttons, etc. and help with administration of the site. Ideally, the person should speak Danish and English. Right now, the job consists of the following to-do list (but if things go well, it could lead to an ongoing relationship): Questions • New products—which products appear here? How are they selected? • Bestsellers—which products appear here? How are they selected? • What decides which products appear on the frontpage? • How to subscribe to Notifications? • What size should product pictures be to see thumbnail and larger size? Changes 1. Remove the area above the orange tabs—move them to the top of the page (one centimetre of flowers above the tabs). Remove [login to view URL] text. 2. The English page is coming up as the default. This should be changed to Danish. 3. Something has gone wrong with the English page. The tabs are the right language, but the menu headers on the left side come up in Danish. 4. When viewed in Firefox—on the homepage the tabs are English by default but the rest of the page is Danish 5.
