Thank you for your question. I'm sorry for the very late reply, but Tim, the owner, has been having some very serious family problems.
1. The contact link for Freemasonry in Kenya is here: http://freemasonskenya.com/contact/
I would be very careful about going anywhere else. For some reason, Africa in particular is host to many fraudulent groups falsely offering to help you join (in return for money, of course).
Also, Freemasonry is a men's group.
2. The only sacrifices expected of a Mason - ever - are his time and, should he so wish, contributions to charity. There are of course annual dues, just as with any other club or organization.
