I need advice to buy WiFi network equipment in an event venue

Hello everyone,

The truth is that I do not have equipment yet and I am looking to buy it. Good quality, best price (Cisco is nice, for sure not the cheaper one). We have a very large property, with some rooms and I would like to supply internet to each of them and abroad as well. I attached the plans.

It is a property with a party room, barbecue areas and several courts. The main room has 3,000 square feet, the smaller rooms are in an adjoining building on 2 floors, the barbecue areas are set aside.

I'm interested in covering an exterior area of another 3,000 square feet and the 2-story building has rooms between 120 square feet and 250 square feet, a total of 5 on 2 floors. If you need, I can provide you with a CAD.

In conferences, there may be more than 500 people. Ideal would be with login, so I have contact details.

I need router, access points and wlc if you consider necesary. And what I need is a recommendation of what to buy, brand, models, how many, among others to be covered.

Thanks in advance.
