I use all types of lifts at my job, from small 25 footers all the way up to 140 feet. I work on everything from 30 Ton overhead cranes to relamping of my company's maintenance base in Ft. Worth (I would tell you the name but I'll give you a hint - We filed for bankruptcy after Thanksgiving ). I'm going to stress something no one thinks about when renting a 'bucket/boom' lift - A SAFETY HARNESS - Believe me when I tell you it can save your life!! I know because I was up in one and a hydraulic hose failed for the basket tilt. If it were not for the harness I was wearing, I would not be typing this reply right now.
Most rental places (RSC, United, or even Home Depot) rent everything from a 'Towable' boom lifts - electric (battery powered/re-chargable) 25'-30' reach (can be maneuvered with 2 people) to the big ones I use (although the 135' JLG I use can run $1000/day - I hope I will never need one this size to put my lights up!!!!) . You also might want to look into a self-propelled one (a bit more money - a delivery charge if you do not have access to a trailer that can haul it - but might be a bit more helpful if your by yourself). Another thing to think about is the bigger you get with one, the heavier it will be. So you might not want to rent one say after a rain (if you don't mind tire ruts in your yard). if you happen to have a few neighbors that would go in for a joint venture, then a long weekend rental (pickup Friday / drop off Monday morning) might be what you need to look into. It can save you many hours of up and down on a ladder!!
Just my 2 cents worth - and PLEASE - WEAR A HARNESS!!!
