It's a tough decision...but think about it. The only way you become good as a groomer...is practice - you may learn the basics at a school - but it's certainly not enough time to be confident to do your own thing. With your schedule, you should try to find a groomer in the area willing to train you - on weekends...... - and then work into it as you grow confident. You have to understand that you usually are paid by commission, and until you are fast enough to groom x number of dogs per day - you probably aren't going to be able to afford to change your career path for a while. GOOD LUCK.
