I don't have a software contract, but I can help you with your second question about signing contracts.

All I do if the clients want the process sped up, is put a digital signature I hand wrote via tablet/Illustrator into the document in the appropriate places. I then protect the document so it can't be edited. Then I email the contract to clients. They have the choice of faxing it back to me, or printing it and sending me a copy. It's normally 2 days max until I receive contracts, even faster via fax.
