What's the step by step procedure to:

1. Re-establishing business with a long lost client.

2. Starting up business with a new client EVEN THOUGH you haven't designed a website by contract for a year?

I have the tools at my disposal, but I need to re-learn them..same way if an electrician decides to go back to his trade after 20 years of doing something else.
I have a contract form that needs revision, a price chart, a maintenance agreement, an old proposal (I can change the names and dates) and an invoice.

However it is the procedure that I need help in from the time I talk to the client to the moment I start work. Also I need to be aware of are the certain things clients will do to pay less money for your services or not commit to your contract with him/her.
