YouTube is a gold mine for how-to videos on home DIY. Might be worth investing time in learning fundamentals, like electricity for one (if you lack the knowledge). Knowing how to use a multimeter for debugging is very useful. Rule number one (for me) is: buy good quality tools and the return will soon happen. A DeWalt power-drill might be expensive up front but it won't flinch when you have to drill through a wall - and again in 10 years!
