+++ CLIENT-SATISFACTION OR MONEY-BACK +++
Dear sir or madam,
I have been developing python projects successfully since 3 years ago.
I have worked on similar projects to what you are looking for, and I am confident I can exceed your expectations.
I will respect and implement your needs from day one, so that you are going to be satisfied with the delivered work.
If you are not satisfied with my work, you may not pay for it.
A short chat-check won't cost you but can bring us together to success.
