Problem with nested IF's and something else.

Hello!
I'm some sort of amateur on complexed combinations of excel functions, so don't judge me for my non"excel"ish language. :D
I want to make an automatic column in my table of sold items, which would calculate bonuses depending on requirements, AND IF requirements met,ONLY then calculate bonuses depending on item price. AND thats a problem.
So, requirements is 355Ls/day or 3 items/day. If person meets these requrements, then he gets bonus. Bonuses depends on sold item price: 250ls (gets 2ls bonus), 300-450Ls (gets 3,5ls bonus) etc.
I need something like - IF(item price>=355ls OR quantity>=3) then he gets a bonus depending on- IF(item price<250;0"No bonus";IF(item price>=250;2ls;IF(item price>=300;3,5ls.
I hope somebody will understand, what I need, and will help me on that. If no, then i will continue to type it with my index :D
Example of material is in attachment. Thanks.
