Automatic spell check online for full site

Looking for a long term work relationship, this is just the first phase of the project. Do it well and I will keep working with you on a regular basis. Write a simple software in PHP. The input to the software is: - Website URL - Google spreadsheet URL The function of the software: 1- Scan the site (follow links and scan all internal pages of the site) 2- Find contact details: Email address, fax number or page with a contact form. 3- scan all the content of the site and find all spelling mistakes and grammar errors. 4- Save all sentences where grammar mistakes and spelling mistakes are found (The full sentence, not just a single word), and for each, save the URL where it was found. Save all of this information to a google spreadsheet. Output: - main site URL, Contact Email address (if found), Contact form page (if found), Fax number (if found),number of pages scanned and checked, number of mistakes found, URL1 (where mistakes were found), List of all sentences with mistakes in that page, URL2 (where mistakes were found), List of all sentences with mistakes on that page, URLN, Mistake list N Every time I provide a new URL as an input, the program must scan, find the information and insert it into the google spreadsheet file as a new line. In your response please write how you intend to implement the program: what type of solutions will you use for the spell check, what will you use for grammar check and how will you scrap the email or contact information from the given site.
