Middlesex County, Ontario | I'm not the guy to write a whole how-to for you today, but I'll add to the convo.
First off: what kind of rovers are you using? Deere does not play well with others. AgLeader and Trimble and the new brands like FJ Dynamics usually do play well with others. You'll have to find out which RTCM messages your rover expects https://www.use-snip.com/kb/knowledge-base/rtcm-3-message-list/
Then you'll have to find a GNSS receiver that is able to send out those messages. Most use a Ublox F9P.
Then you'll have to decide how to link the base station and rover: radio or internet? Most use internet as it is easier.
If using internet; you'll want some kind of computer that takes in the GNSS data from the receiver and puts that data on the internet. There are lots of choices. Many use a Raspberry Pi single board computer (SBC) with RTKBase software. Some use a Windows machine with SNIP Caster software. Those are probably the most popular two.
Then you'll have to decide what the internet path from your base to rover looks like. Will you connect directly using port forwarding, connect directly using a VPN, connect indirectly using a remote server (called a caster)? An easy way that a lot of people use is to use a free caster service called rtk2go.com
Then you'll need a way to receive the GNSS corrections in the rover. Can your GPS monitor connect to the internet directly? Will you hotspot your phone? With or without a serial bluetooth link? Will you get a little SIM card router?
There are way too many different ways to do it, and you'll have to read about them and decide for yourself what works and what your comfort level with setup is. https://discourse.agopengps.com/ is a good source of information.
My setup uses a UBLOX F9P. I bought the F9P on a small development board, and then created a custom PCB that connects the F9P to a raspberry Pi. The custom PCB also allows the Pi to be powered over ethernet, so I have a single ethernet cable running up the chimney and no separate power cable. On the Raspberry Pi runs RTKBase, a free software. I did not do this the easy beginner friendly way, I did it in a way that I felt was a very clean and compact way, and I have some redundancy because the F9P is exactly the same as what's in my tractors, I can pop them out and swap them if needed. In the tractor I am using AgOpenGPS on a windows tablet, and the tablet has a SIM card or I hotspot my phone for internet.
