For project work or large parts orders we will send you a proposal via email. To place an order based on the proposal just follow the instructions in the email to e-sign the proposal. If a pre-payment is specified in the Terms box of the proposal, then you can either mail a check for the required amount or place an online payment on our Payment page,  If you have any questions regarding the proposal or need to make changes, please contact the person directly who sent it to you.
