Do not kid yourself. Doing the work yourself will in fact provide a cost-effective alternative route to paying a second party outright. While you may spend a lot of your "free time" work on the project, you will save your money in the end.
First and foremost, you must decide how much you are willing to spend. Are you using a loan for the project or are you working on "out of pocket" cash? Once you have decided how much you are willing to spend, begin to look at the equipment rental companies on the internet. Next, choose a company that suits your budget and proceed to contact them for additional information. In doing so, you will gather all the information you need to complete the equipment rental purchase.
