An EFP is where you take a studio type of set-up (cameras, mixers, etc.) out into the field to create a multi-camera production which will require only the minimum of post-production work to be done, later on. Essentially, it's what the television stations would call an OB (outside broadcast), but this is for recording or local coverage, not direct broadcasting. If you were to transmit from it, then it becomes a real OB.
The picture shows some of the equipment that could be part of the kit, giving you some idea of the transportation requirements (the size of the equipment, and how much equipment there might be, dependent on the needs of the particular production). There's various different cameras, mixers, et cetera, that we can supply, as appropriate to the job, but they're all similar physical sizes.
Depends on equipment, crew, transportation, and time.
Much more equipment is listed on the equipment hire page, and we acquire more equipment all the time.
