Need Scanner Software Help

[EnFoRcEr!!]

Well, to make a long story short, I'm working with an HP Scanner that has horrible software. The user wants to be able to simply hit the button on the scanner, and have it auto-scan the PDF file into an e-mail document to send out. The problem is that short of using the scan function from Adobe itself, there are no option available to adjust the quality/file size of the PDF file within the HP software. The PDF files are automatically scanned as color images, and our anywhere from 400-800kb A PAGE! Does anyone know of any compatible third party software or something that may be able to remedy this issue? Thank you ahead of time for any help.
