Need PA and sound dude

Anyone have any experience renting a PA (possibly lighting as well) and a sound dude for a day?
Anyone have a recommendation for a good company that provides such a service?

A friend has the opportunity to provide enetertainment for a rather swishy upcoming affair. She’s asked me to help with a few things. The only area where I plead basic ignorance is in recommending a good company to supply this service. Like I said it is a swishy affair, meaning very important for us, so quality of equipment and reliability are very important.

I’m pursuing a few avenues for sorting this out, but if anyone here can recommend a company and provide a phone number or avenue to pursue, it would be greatly appreciated. much thanks!
