Basic php-mysql script

Hi, I need to create a php script, that allows registering disabled children with their details (such as height, weight, skills, CV, pho etc). More than one photo should be able to be uploaded and one of those specified needs to be set as the main photo. The user who uploads the details will be different then the children in the [login to view URL] there have to be seperated section for registering users; And then when users are logged in , they will be able to enter details of one or more children. Every user will have a unique login username and password Only the user who did enter the child details the first time can modfiy it later. Once a new children details are entered, they still in stand by (not publicly viewable), until validated by administrators (administrators are users whith admin [login to view URL] are different then normal users, so interface should be different) A third kind of users, consultants, shoudl be able to list the children on the database by different search criteria, such as age, height, gender, skills (keywords) or a mixture of a few search criteria to narrow down the search. The relevant results should be displayed as photos with names, age and location (city). There should be a 'more details' under each child search result which enables other information such as height, waist, hair colour, eye colour etc etc to be displayed (in a lightbox/overlay on the topage).(ajax) Finally, a feature for the administrators to be able to (via the back office) select multiple children and email their photo, name and age to prospective clients.
