Prom Night Limo on Tight Budget in 80s Sunglass Icons

My daughter’s prom is coming up and she’s dreaming of a stretch hummer, but our budget is quite limited. We looked at several local limo companies and their quotes were very different. I heard that some broker services can get better deals because they work with many operators. We want a safe and fun ride with a friendly driver who knows their stuff. How can I find affordable but trustworthy limo hire for prom?
