Boy, this has actually been one of the hardest parts of all this. I have a van to move all the equipment. So, as you can imagine, part of the price depends on how far away your show is (I'm in SE Orlando).
Anyway, to at least give you a "Rough Idea", figure on $100-$200 per night depending on distance, type of event, number of bands (i.e. Battle of the Bands). If you're a band and need a system for both Friday and Saturday, I can offer some sort of "Two Night" discount as well.
Really, the best thing to do is just give me a call, tell me what you need, and we'll figure out a price that's fair and that you can live with. One thing I can tell you for sure though,... The price I'll give you will be "Noticeably Less" than what you'll pay anywhere else for a similarly sized system. How do I know that??? Because I did a lot of investigation on renting systems for my own band before I bought this system. Conclusion was: "They're Expensive to Rent" You'll be happy with my prices. Give me a call and we'll talk.
