164263 gas price checking script

I need a script updated or created from scratch. I had it written about 3 years ago and some of the sites it checked will probably need to be updated. The script needs to take input from visitors to my site (ZIP code, and frequency) and go out and fetch the data requested, compile it into an email and send it out to the subscriber at the frequency they asked for. I will also be needing a site created for this. this can be a part of this project or I can list it separately. Please ask for clarification as I know there will be questions. This is a fairly urgent job. I would like it completed with bugs worked out withing 7 days after selecting winner. Please put "gas rocks" in your reply to show me you are not a bidd bot. In summary. I am looking for a script for a site that will take users input, gather the gas prices from the internet, and compile them into an email and send it out to the user. Thanks
