I would like you to develop a php installation script for me. The script must be configurable. Confiuration is expressed in terms of exsisting php object-oriented api which store information about page headers/content, fields shown on the form (name, label) and validation procedures to apply (which existing class to call to validate posted form data). Coding class performing actual validation is not included in the task, your script must only invoke that class.
Looking for your bids. Please describe what are you bidding for. E.g. whether you solution will use ajax to perform validation, wether css coding is included in the bid and so on.
