9723 PHP Conversion

I have several sites (3) that have scripts and pages written in PHP4 that need to be converted so they run under PHP5. Each site has 3 scripts that generate dynamic pages under PHP4 but generate pages without content under PHP5. I'm assuming the variables have to renamed or the data has to be called differently. If you know how to do this or have done it before I would like you to bid on a per site basis and to also provide your hourly rate in case other pages have to be updated. I need a person that communicates well. I don't to deal with people who only communicate when they feel like it. Give me a price and a schedule and stick to it. I can provide a sample script if necessary.
