How is their network setup currently and what kind of network devices do they have? (switches, routers, firewalls...etc.)

If I understand your question, you are wanting to attach them to your main network and provide them with Internet and office networking so they dont need their own system.  Is that correct?

the opposite. i need to break off of their network. if they connect me to their lan switch, do i need just a router or wireless router ? or do i just need a firewall ? i need to be off of their network ?

If you are piggy backing on their network, it is them who control the access, not you.

The solution can be difference based on what type of network devices they have.

This will involve three routers.  One would connect to the Internet connection.  Then, two more routers plug in to the LAN ports on that router.  That would allow you to share the connection with two routers while isolating the workstations on each network.

See the attached file.

I do this for a coffee shop next door to our office.  I have a router and firewall setup.  Then, their network has their own router, as does mine.  Each network has its own network address.

External:  66.xxx.xxx.xxx
Mine:  192.168.10.x
Theirs:  192.168.20.x

Essentially, you just need to plug your own router's WAN port into their network connection and enable DHCP.  That gives your network Internet access.  But, if you and they both want to be isolated, then you need to do what I listed above.

Yes!  That is what I did.  Just make sure that their router and your router are using different network IP address ranges.  If you buy a consumer router, it will come pre-configured as 192.168.1.1 or 192.168.2.1 (or something similar in the third octet).  You will need to make sure that your network ID and theirs are different.
