I installed white cabinets, shaker style, from Home Depot.

I install networks and low voltage cable and hardly anything in this city.

In Atlanta we pay about 180 bucks per replacement window including installation! 

I know as you mentioned classic cars are a big thing in our part of the country -- could  you start some sort of Guys/Car hangout - use the front office as a clubhouse - lots of old auto memorabilia there and in the warehouse (plus you'd have the fun of shopping for it), maybe install an automotive lift or two, great lighting - fire suppression system (would definitely make your insurance cheaper)? 

Get a counter brush to use  when you install and run it down the side of the plank to get debris out of the locking system.If you have a Menard's in that area see if they have the Evolve plank.

You could install additional blown-in insulation which won't cost a lot, the reduction of the R Value is both energy saving and helps the AC usage. 

Couple that with Arlington's restrictions on repairing/replacing railroad ties and we were basically forced to install a new stone retaining wall, especially since some heights of the wall exceed 5 FT which required additional engineering requirements. 

I assume you are talking about a whole house filter, where you can install it yourself.

  $700 + wires + installation labor.  

After that rehab, he ended up going to satellite dish installs and seems a lot more engaged than he was doing the rehab stuff there for us at the end.At the end of the day, it worked out fine for us.
