4' x 8' alu-panel printed/laminated double sided.

I think you are low if you are talking a piece of Econolite. I would say $650 for a double sided 4' x 8'!

and you should always charge for installation. how did you mount it between to posts? Did you have to fabricate/buy brackets that you didn't charge for? hardware? Do you have to have a contractors license to do work in your town? Permit? These things all cost money that you should be charging for!

Don't be the "the guy down the street said he would do it for $500 bucks and hang it up for me too" guy!

 

Out here in Calif I get 350.00 per side...plus install time for 4x8 alu-panel signs.But we're over priced housing central...lol

 

i'm in alabama home of the lowballers and i would get $500 or so for single sided installed (simple screw onto bldg or exsisting post) i know you don't have a lot in material cost but you have a several hour investment in your time and you must charge for that. my small one man shop has $4000-6000 in bills each month and then i need to make enough to pay me and make some money too... don't short change yourself... you'll be working really hard just so you can eventually close your doors. if you are not gonna make money in biz you would be so much better off just getting a job and making it home with some money.

 

You'll never be shafted for "being too high"... in this biz, and the way things are with fly-by-nights operations, you'll be greeted with a "More power to ya!"
