Where can I find the address of the bank's central clearing house?

[JonnyBoy12]

As most of you know I have been considering becoming a courier for some time now. I am now fully kitted out for this and am actively seeking work. I understand that the banks need data shifted at the end of each working day and need someone fast and reliable to do this. I would firstly like to write to the banks offering my services and then the central clearing house as well.

Can any of you tell me the addresses of the headquarters of the main banks and also the clearing house for these banks?

Thanks in advance for your kind and helpful answers. I am 'banking' on you helping me out as have been out of work for a year now.

To get a full list I don't think we could do better than to do a Google search for you.
If you do contact the banks I wish you luc but I would expect it to be a very competitive market with well established companies in there. They would also expect you to be able to show a proven track record of deliveg promptly every time and have 100% foolproof security sytems.
