After three months of struggle i finally got a contract

My agency says that I need to register for the umbrella company before the offer is being rolled. She said if i wish, i can even do it my self. Now my problem is..
1) Which umbrella company should i go for.
2) How much can i expect after deductions.
3) Dont ve an UK address, and am planning to for HSBC passport account, is it okey, or should i go for something else, any feedback on this...


Waiting for your inputs guys..
