Best auctioneer sound system? Please help

I am an auctioneer who sells to both inside and outside venues. I want to upgrade my sound system. I want it to be somewhat portable. Most venues with systems just are never good enough. I conduct large inside and outside sales. I need to be be clear yet loud enough for my audience. Any help or ideas would be awesome. I don't mind spending money but want a great product not just an overhyped brand.

Location. I generally put two large speakers in the front. Could you recommend a better system for inside/ outside sales?

I am looking at possibly getting a long range hailer style system. Would you recommend the best one in the industry? It would be cost effective to use just a hailer system for everything. How many speakers and where?

Who makes the best handsfree mic out there? Would prefer a wireless handsfree system.

Would you use a traditional style speaker for indoor and smaller audiences?


I was also considering a smaller system which would be portable. Something like a hailer style speaker and mic incase the venue doesn't have electric or as a backup because a failed system can lead to a sore voice.
Thank you in advance for your help!
