floor boxes product question

[highvolts582]

I am going to be wiring a computer school wood floor carpeted has basement I am going with MC wiring any one know of an inexpensive receptacle box and cover that will except MC. I am having trouble finding a reasonable product that does not cost a crap load as floor boxes can do. and simple to install there may be a ton of em so are all floor boxes firerated? I have seen metal boxes with brass covers and a single outlet for like 40.00 each thats fine but if i use like 50 of them does that give me a fire rating problem?

Thanks,

I just got mail from Wiremold, they have a rated floor box but be prepared to pay for it, no way around that.
