New Customer Thank You Letter Does Anyone Have A Good Sample Letter To Ask A Customer To Start A Project They've Already Paid For?

Does anyone have a good sample letter to ask a customer to start a project they've already paid for? - new customer thank you letter

I am looking for a sample letter that asks a client to start working on a project that has already been purchased to give, can, but have been delayed. He has closed in the pipeline for nearly two years and must send them. I know that the economy is rough and capital is scarce, but I hope to help some of you! Thank you.
