Welcome aboard Mark,
Glad to see you here.
Look forward to seeing your progress on this job. When it’s slow, sometimes you do what you have to do to make a living. I like how instead of just lowering your price you made adjustments to the materials and whatnot. I always do the same, tell the customer that we can eliminate this or that, change sizes, materials, whatever else works to lower it. Usually this gives you a good idea where the customer stands. Lots of times after I suggest the changes they will pony up the truth and say they don’t want to make the changes and lets just go with what you had.
At any rate, good luck with the build.
Figuring out how to do something you have never done is what makes a good challenge.
