Does anyone know of a formula I can use for a commission structure?

Whatever the cost to print is, I need a formula that looks at the value in that cell and calculates the correct commission flat rate or percentage in the commission cell.

Printing costs $750 or Below = $150 Flat Rate

Printing costs $751 - $1,499 = 20%

Printing costs $1,500 - $4,999 = $300 Flat Rate

Printing costs $5,000 - $5,999 =10%

Printing costs $6,000 - $9,999 = $600 Flat Rate

Printing costs $10,000 and above = $1,000 Flat Rate

Can anyone help me? Thanks in advance.
