BR,
I do not know if A-Plus will sell gear only. I know that B&H has a lot of gear on-line. Great place to go to just to see the options, capabilities and the costs.
Here is a link:

I have A-Plus in NH. I did the house in Ma and the condo in FL myself with gear from B&H. It is all fairly straight forward.
Good luck!
