Dear Sir/Madam, I am a highly qualified Network Security expert.
I am very interrested in completing a project similar to yours, and extreme care will be taken for PCI DDS compliance to be ensured. I believe you are integrating with a credit card system (such as Visa API) and a very high level of security will be required. I am prepared to do all in a considerably short period of time, Kind Regards.
