Is the ACM you get from them full size? We use an oversized ACM sheet so that after the route, the sign is still true to size. This helps when trying to slip them into a frame.
Also, we sell the whole
real estate sign kit here frame and all for about 1/4 what you are retailing to the customer (Of course we are wholesale only) and we really don't sell that many. What you guys can get for these kits surprises me a bit. We should sell 10,000 at the price we have them for!
