need help for a Database in a Money transfer business

i have my own dbase here, is this correct:

branch(branch_id,branch_name,branch_address)
teller(teller_id,teller_name,branch_id)
client(client_id,client_name,client_address,teller _id)
sender(sender_id,client_id)
receiver(receiver_id,client_id)
sender_receiver(id,receiver_id,sender_id,amount)

branch has one or more teller.
teller has one or more client.
client has one or more sender or receiver.
sender and receiver has one sender_receiver.

money transfer business is a kind of business where a sender can send money to the recipient and the recipient can claim money from the sender thru the help of the teller.

:eek:
