Many people can't afford to pay a repairmen to change toilets, stop leaky pipes, replace wall switches and eliminate mice from the house. How did you learn to make your own necessary repairs and updates?
My Dad was in construction so he taught us a lot. Most people are not that fortunate. A friend of mine actually tackled plumbing and electrical by studying You Tube videos. So far so good. Not sure I'd be that courageous!
We learned young, but we continue to learn as products, therefore techniques, change. YouTube videos and websites do offer great tutorials.
That said, consider bartering with those who know how to do what you need done. A meal delivered to a handy man's family might work for replacing a wall switch or few. Setting up or repairing a computer/phone might get leaky pipes fixed up lickety-split. Mowing a plumber's yard for a month might get a toilet changed out. Making handmade cards/gifts for a mouse catcher's services or screen door repairman's talents might serve everyone very nicely. Your talents may be as valuable to someone else as theirs to you!
