I require 50% deposit upfront. After you pay the deposit, I will prepare a short example. After you agree with it, you pay the rest and I send you the final output.

Paypal: Pay for goods or services

I accept payments via ­PayPal. It is safe for both sides. It is covered by PayPal buyer protection program, but ­ PayPal charges me around 5% from the price of transaction. This fee will be added to your payment. I will send the invoice to your email address (with the 5% fee added).
