BPO contract for a good BPO company

My client has set up a new venture and seeks a BPO company who can market their business in INDIA, USA, PAKISTAN, AUSTRALIA, CANADA, UK Please this is a very serious on going project for a period of 6 months, this will be extended to 2 years provided targets are met. Also any bidding person or company should not just bid but ask the relevant questions so as to know the targeted revenue of my client. This way proper structure can be drawn so as to achieve monthly, quarterly and annual budget of the company. thanks mark
