Electronic Signatures

I was not really sure on the skills it takes to write electronic signatures. I need to create documents that can be signed directly from my website. I would need the program to do a couple things. Record the IP and time is was signed. The fields my customers would use are between 2 - 4. The Document should also date the document in about 4 locations on each document automatically. Then once the information has been inputted and submitted it would like for it to create a PDF file and email it to myself and my clients. Anyone here got the skills it takes to write the script for this? I have a website address that is live (just not linked anywhere to provide an example of what I'm looking for). The main site is active and do not need anything on that right now. I would like to find myself a go to person. Hit me with your best quote and a couple examples of your work. email me directly Justin at fullloop dot net ;) Take care
