Signature Capture into Excel

[FaithOmitted]

I hope someone knows something about this:

I'm looking for a program that preferrably takes a customer's signature for a work order and directly inserts it into an excel file, perhaps in a designated cell. If this isn't possible, I know there is software out there which can take signature (like in the Notes application), save it as a .gif or .jpg, and then I can import that into the excel file. If this is going to be what I have to do, does anyone know of a good program for this? I've only seen a couple and none of them have free trials, so I am asking your opinion before I buy. Thanks folks!
