Google script / spreadsheet

I've created a form on google drive which my customers can fill up online for booking. The results of this form go into a spreadsheet on google drive and I added some script to this spreadsheet so that it also send me automatically an email with the results of the form to my email address for each new entry. This form has many questions including name, email, address, birthday etc... I would like this form to also: - automatically update contact informations in google contact - send an email to the client on their birthday I probably could do it myself if I had the time, but I dont... thanks for your help. Looking forward to the best bid :)
