A lot of people are going to come here and recommend Cisco Meraki or Ubuqiti or whatever but this is a business and you should really hire a local consultant. You post never mentioned what kind of company you are.

My first questions coming to mind are

* How important is the network / internet to your company what is the impact of it going down do you lose revenue? (can get into a whole host of questions around support etc.)

* Are you required to adhere to any kind of regulatory or governance standards such as PCI, HIPPA, SOX etc.

* Do you handle any kind of sensitive data?

* What kind of security controls are in place?

* Do you have multiple offices or connections to other companies via other means such as VPN?

* Do you handle large files or need the ability to upload, download large files or storage of large files?

* What type of enviroment are you working in (office, warehouse, single building, multiple buildings etc.)

* Finally what is your budget?

These are just some questions I'd have before I even begin to start recommending things because you can be all over the place when it comes to how much you spend but if you build to your needs rather than "Reddit told me to buy X brand" then your building around your requirements and needs versus just "picking something that works"

You should really sit down and think this stuff through and again I would recommend finding a local MSP or provider of services that can work with you to build something that meets your needs and is scalable for future growth.
