Computer science work please | Computer Science homework help

 I need someone who knows a bit about business information systems.

The work is about Tesco (a huge company in the UK) so this will be easier for someone in the UK and what you need to do is: 

e) Draw and give description of a simple DFD of its Payroll system.

f) Give the organizational Structure of the organization (you need to search and refer to your textbook)

 g) Describe and comment on their outsourcing and their international connection/investment (Does your chosen organization have some operations which are not done internally, any link with operations abroad?)

This is only level 3 work so easy for someone who knows about it, and the eBook for f) I have on kortext ill give you my login

   Let me know questions, if you can do, and price thanks
