[Skunkworks] Google Spreadsheet scripts (send attachment from Google Spreadsheet)

Skunks, I have a challenge here, I have a Google Form that is embedded in my website (www.opencast-labs.com) that users fill when they register upn visiting the site. I want the Google Form >>> that lands my data in Google Spreadsheet to automatically send an attachment (SendMail script) to the visitor ( using the email address supplied ),. Please send me suggestions and or quotation of how much it will cost for one to develop such a script ( bear in mind that I use Google Apps and would like to have data revolve around it). In the next phase I would like to have the CRM am using communicate with the spreadsheet. Inbox me on: david.kandie@opencast-labs.com And please no LMGFY >>I tried it but in vain.
