186652 Quality PageRank/SEO Checker

I need a script that is similar to the following Web sites: - [login to view URL] - [login to view URL] - [login to view URL] These are the primary features that I want in the script: - Show PageRank (with and without WWW) and verify if it's genuine or fake - Show the number of backlinks on Google, Yahoo, MSN, Alltheweb, Altavista (with and without WWW), plus show the total number of backlinks - Show the number of EDU and GOV backlinks - Show any links from Wikipedia, Technorati, [login to view URL] - Show the Alexa rank and Alexa graph - Show if it's listed in DMOZ, Google Directory, and Yahoo Directory - Show the domain age and number of records in [login to view URL] - Include a "PageRank badge" code that users can copy and paste to show that a certain domain name has been verified by my Web site The script must be written in PHP, and must be fast, accurate and reliable. If you have an existing script that has some of the features listed below, I'll pay for the script and customization to meet my requirements. If you don't have an existing script but you can code one from scratch, that's also okay. Please show me a demo if you have one. I don't have a set deadline for this project, but I would like to finish it within two to four weeks. If it can be done in a shorter period of time, so much better. Thanks and I look forward to receiving your offers.
