Just how far out in the wilderness are you?What's the size of the population within a comfortable driving distance?
Time to move..
Does the business have a website?? Google AdWords is the best form of advertising (outside word of mouth)
Well, good luck with that. People are no longer sociable enough for that to work.
I would use the server you have to make a website for the business. That would be more useful. Domains are 10 bucks...
You dont really get a lot of spam calls. Most of the time what we get is people asking for the electric company.... But, spam calls are a part of business. Most of the time, you cant tell a persons house from close ups of their cabinets, doors, ect. If someone sees them and wants them removed, you could remove them for them.Honestly, though, it you did good work and your customer was happy with you they'll never complain about you posting pictures of their house online.You could also google "carpentry work" and see lots of examples.
