I Started A Small Rental Company And Would Like To Know How To Set Up Quickbooks With Rental Equipment?

I need to know how to set up quickbooks in such that I can generate a report which will tell me the following things:
-Where and how to list my items in my inventory which are never sold and only rented out to customers
-At which point I have made back the cost of purchasing the equipment?
-Track Inventory as far as how many is in stock on a daily basis and how many is out being rented
-Profit from rental income based on each job
I am new to Quickbooks so any advice will help. Thanks so much!
