Proofs for Full-time and Partime Earnings

[HadiHasan]

Hi
How about showing the part of the earnings as part-time income?
like consultancy work etc. Suppose showing the earning as follows
60-70% as Full time
30-40% as Part time
For full time providing two evidences
1) Employer letter on company's letter head( with sign and
stamp), showing the annual gross income with all allowance from
period xxx to period yyyy.
2) Attaching the original payslips (not photocopies)

For Part-time showing also two evidences
1) Part-time Employer letter on company's letter head (with
sign and stamp) showing the start date of part-time and mentioning
the hourly rate like @ $100 per hour with the list of Systems he is
responsible.
2) Attaching a detailed letter listing down the amount and
number of hours for each of the 12 months like Dec 2005 to Nov 2006.
This all info on company's letter head with company's account's sign
also possibly can stamp too. Since no payslips as the amount is paid
each as cash.
So guyz ur comments on this
