PHP Email Grabber Tool Required

I am after a PHP tool that allows me to search a website for email address. The spec is as follows: 1. PHP tool required 2. I need to be able to supply an unlimited number of URLS to the tool 3. I need to be able to specify how many levels deep it will search on each website i.e check the only links off the home page i.e one level deep 4. If there are more than one email on a website the tool needs to grab all of them 5. results need to be listed and be able to be exported into an excel spreadsheet. 6. Results need to display URL and all email address extracted To summerise I would like to input a list of unlimited URLs into a tool, then the tool visits each website on my list searching a set number of levels (pages) on each site looking for email address. Any email addresses found need to then be extracted and put into a list. The tool then moves onto the next website from my list. When the tool has finished searching all the websites and has extracted all the emails I need to be able to export the email list to an excel spreadsheet. Please ask questions to ensure no time is wasted. I need the tool within three days of the bid being accepted.
