25 of the heads are in a parking strip measuring 5x130. Does that help. And, in reference to $11K figure, if I am $4K low(bearing in mind this county is one of the wealthiest in the country) what now? I, apparently, have been trying to figure out too much of this on my own in an attempt to get every dollar I can into my pocket so I can build this business more quickly. Materials will be about $4k-$4.5K. Do I tell the client; I made a mistake...it'll be $XXXX more. I don't think that will fly. I don't have a contract yet, so....go back with a higher bid and refer to another contractor when they tell me to go jump in the lake? My PT gig ended and I turned down another job based on the enthusiasm the client had going in...I assumed the sale...and need it badly. The design was created by a system designer at the supplier I'll get the system materials from so I'm gonna bounce my bid off of him. Any advice on how to handle this situation would be greatly appreciated. And, thanks for the help so far.
