Woah, I wasn't insulting the trade. I am a graphic designer, just in a different way.
Yes you are..
I have never hired a Graphic Designer. I can do it cheaper. Why pay a good designer big money when I can do it myself for about half. Even though I have no clue i can still do it. But just because it looks like crap doesn't mean its bad. My customers never complained. In fact they never come back. I get lots of new customers every day. So I guess that means I am doing good...
I think you are acting like a graphics designer. And not acting like a smart business person at all. If you had any moxy you would be hunting down a pair of local printers and do wholesaler deal with them.
Why would you want to cut out a local expert? I don't get it. Oh yes, now I remember, Graphics designers think running a large format printer is just like running that desktop laser. Thats your second mistake. Your first was dissing those who do this work. The third mistake is thinking you can do it yourself cheaper.
Just think. You get to buy colormetric equipment to align your entire print loop so it prints the right colors. Wow, That only adds on about 3 grand if you do it cheap. Then you gotta spend another grand to learn how to run that stuff. Wow, then you get to spend another 4 - 5 grand learning how to run your printer. Wow, then you got your down time waiting for your techy to fix yoru printer when it goes crazy. Then you gotta pay your techy and train him. Oh yes, I forgot, you can buy a warranty package for another $2500 a year. Yes that will get you into bizz.
You can't save in the short run.. and the long run will be out there around 8 years to break even. Meanwhile you will start seeking out local work to pay to keep that machine busy. (You already are) thus removing real sign and banner printers from the loop.
So, dream on. And when your local boys find out you are taking away work to pay for that printer,, and see you are subsidizing that printer via the newspaper... They will soon mount a quiet campaign that will silently cost you revenue from the paper.
