When I was beginning study for my CWI, my job at the time was a maintenance welder for Boeing so I had loads of free time at work :) I used that free time wisely and studied as much as possible, sometimes maybe up to 6 hours daily and then did an hour or 2 at home. I did that for 6 months then took the 5 day Seminar offered by AWS - which I HIGHLY recommend. Essentially the seminar is NOT going to teach you what you haven't already learned; it is an intensive review and to some extent, provides some extra tips on best ways to pass the exam, which is offered directly following the seminar so its all fresh in your mind.
Different study habits work differently for different people. Since I've never really considered myself the sharpest tool in the shed, I've always tried extra hard, the one thing I have no lack of is motivation and its proven one of my best assets!
As for finding employment, obviously you have use of and knowledge about computers and internet, there are no shortages in opportunities but you should be prepared to relocate often, following the work. (Speaking from my own background which is construction). If you don't want to do a lot of moving around while establishing your experience, you'll find less opportunity and obviously less pay.
Best of luck, keep posting. This business has provided me with over 35 years of continuous learning, I've never been bored with it and never regretted my career path!
EDIT: Just adding a P/S: My experience was almost identical to yours when I first sat for my CWI, that leads me to believe if you follow good advice and study hard you'll have no problem passiing!
