Drywalling ceiling sucks. Walls aren't to bad if you have patience. Priority one is straight framing. Everything depends on it for a nice wall. Mudding and taping just takes time to get right. Watch some youtube videos. But it sucks, and is messy. Alberta Drywall Supply had the best prices when I was looking, and will deliver to your basement(huge bonus).
Electrical isn't all that difficult an area to save loads of money. Most of it is just tedious repetitive work like pulling cables and stripping wires. Buy this:

It has everything you need to know about wiring to code, in easy to understand language(and pictures!). I did my garage with the info in it, past inspection no problem. Well worth the money, as understanding the code is tricky, and finding info online specific to Alberta is even harder. I had an electrician install my panel and main hookup, as I wasn't permitted to do that part, but I did everything else, including the in-panel stuff. Get a good wire stripper and a sharp knife, all you really need. This place has way better prices on circuit breakers than the box stores, and get wire by the spool.
