AutoIT script for mass messaging in a website

I need an AutoIT (AutoIT, not Visual Basic as I was forced to set in required skills) script for mass messaging on a dating website. Bid for an average site. I'll give you the possibility to revise your bid if you find particular difficulty after I'll give you the access details of the site. The script must log on file its operation (eg. the addressee, timestamp and a counter of sent messages). It must also check the after-submit page to verify that all the messages are successfully sent. If there's a limit in the frequency of messages, it must take account of it. Thanks in advance (Budget around $30-$50)
