Hi, I think I might be able to help you out with the script you requested, but I was wondering if you could possibly post a little more information.
I understand that you wanted to be able to access a client's information from their home, what sort of business is it, and what sort of information needs to be tracked? Also, did you need to be able to handle credit cards via the script as well so that you can have them pay when you are done with the job?(I'm assuming it is an in home service of some sort)
