Hi,
After reading your requirements, I can safely say I am good with all except, I am not from any of your preferred countries, though my country, Guyana (located in South America and not Africa), was once a colony of Great Britain and I am available but not for the full 2 - 3 days (mostly available in pm EST).
Nonetheless, I am sure I can assist you with whatever your needs are.
Let's discuss.
Regards,
Teddy Cummings
