Acme General Woodwork and Davis Junk Company in Vancouver

First things first: You might say "I read about" or "I came across," but one would not say "I read across."

As for the substance of your question: Woodworking means carpentry, and usually means carpentry requiring a high degree of skill. It would mean people who make furniture, or cabinets, staircases--the kind of working with wood for which one needs skill and experience. A junk company implies someone who picks up discarded items--broken furniture, broken-down appliances, scrap lunber, scrap metal, old bottles and cans--in order to salvage anything useful from them.

In my opinion, it is unlikely that anyone would use such company names, though.

Thank you so much!
