If you are looking for a local neon sign, it is probably to advertise your business. IF that is the case, you probably have no better option whatsoever than to go with a local neon sign maker. The first reason for this is price. Neon is expensive and it is extremely difficult for anybody to make this in a cost effective way. Therefore, you will, in all likelihood, have to pay a very high price no matter who you are going to buy from. This is one case in which there are not that many economies of scale. They do exist in as much as a large company may be able to get supplies for less, but still, the same amount of labor has to into shaping the sign no matter who makes it. Because of that, the price of the sign itself will not be much cheaper at all if you go with a large company. In fact, any savings that you get may be wiped away by shipping costs, based on how large your sign is.
