Advice on Renting Construction Equipment

Hello there!
My friend and I decided to start a small startup construction firm and we registered our company legally by satisfying all the necessary safety needs. We also employed some workers in accordance with the industry's regulations. We signed a new contract referred by our friend and the work should begin in two weeks. We will need aerial equipment to begin the project, and we decided to rent it rather than buy a new one for our business. By renting we can avoid the travelling cost from one location to another. We're considering hiring aerial equipment for the first time, so we'd appreciate any advice from anyone who has done it before.
I look forward to hearing your suggestions.
Thanks in advance.
