Everything you wanted to know is the signs. I need a sign on the shop, where to begin, where to order what? In the first place I recommend, to determine the budget, at least to understand the procedure, how much you spend. If up to 25,000 rubles, then you not get a big light box (up to 8 square meters) is the only manufacturer of advertising design, this amount does not include installation and registration, which can be much higher than the cost of the signs. In the simplest If installation will cost about 7,000 – 10,000 rubles. This is a setting on a flat wall signs with a connection to the wire you inferred. If the box must be mounted on the uneven surface at some distance from the wall or in general installed on the hood or roof, then just have to shell out an additional metal structure, which must not only correctly and accurately to cook, but the paint (preferably powder as this will allow you to permanently avoid traces of rust). In this case, the cost of installation could increase to 2 or more times, and if necessary carrying out electrical work (wiring in the ripple, the installation of machines, devices, breakers, sensor or sensor dark time), then cook for another few hundred dollars. But in any case, do not skimp on the electrics. Continuously burning sign, short circuit, overheating the cable, here's the result of savings, but the result of a call Electrical wiring and modifications (both outside and inside signage), which will cost significantly more.
