You can buy wall mount racks that lock. APC makes them. The type I'm talking about though will only hold patch panel(s) and switch(es).
It would be worth your while I think, to buy and use one of these. Pull all cables and have them terminate on a patch panel (or panels as the case may be) in the locking wall mount rack.
If you also need to house a server (or servers) then a server rack would be preferable. You can also mount patch panels and switches in a rack like this.
The amount of time needed depends on how many cables you'll need to pull. If it's 40 to 80 I could do that in a day including punching and testing cables as well as mounting the wall mount locking rack. Installation of the switch about 20 minutes and if it's not a managed switch, configuration time for the switch is nonexistent.
As to cost, well, you'll have to price out parts yourself. Having no idea where you're located means I can't give you an accurate estimate. Besides, this isn't that hard to do. Contact local suppliers and get price quotes. Go with whomever gives you the best price.
I suspect with POS devices (point of sale) you will require an internet connection. I would recommend going to highspeed and using a SOHO router to protect you.
