Good morning, I understand you're looking for people who can teach English.
I have the "qualification" of being a native English speaker, but I have never heard of Celta, Delta or Trinity Desol as any form of qualification, and I don't have a Master's degree. These are not necessary to work legally as a freelancer though.
I do, however, have an excellent grasp of the language, and have no qualms when it comes to teaching others how to use it correctly. I enjoy helping people, and as English is the international language of business, it would be an important task which I would treat with great patience, and the utmost care & sincerity.
Unfortunately, Freelancer's rules do not allow communication outside the site, so you are in violation of the terms of service both by asking for email contact, and for providing an email address with which people may contact you. You also have no verification aside from email, and your account is only 3 days old. As a result, I will not be sending anything to your email address, but if anything else I've said regarding my own few qualifications is acceptable, please do not hesitate to contact me using the site's private messaging function.
Best regards,
Tyler.
