I've found that to find shops that I liked, I've just had to try out a lot of shops. I ended up liking and scheduling lots more shops that I decided to try out on a whim, thinking I wouldn't like them. And I've had shops that I was sure I was going to love and ended up disappointed with them and not wanting to schedule more. Of course there have also been shops that I didn't think I would like and yep, I didn't like them
What works for me is to find some basic categories of shops that are often available in my area: restaurants, gas stations, cell phone shops, storage facilities, banks, etc. Then try out one or two of those jobs for each of the MSCs that offer them. Once you find something that you like, you can figure out when that MSC posts them each month and sign up for as many as possible. I've found that I like the jobs even better once I've done them a few times, so if there's something that is relatively profitable and you don't hate it, try it a few more times to see if it gets easier as you get more familiar.
Since you've removed some of the emails you used to get, you may have to try to turn them back on, or check the job boards manually, at least for awhile as you identify that elusive job type that you like. You may need to branch out if you don't find it right away: maybe you're not really the type to enjoy Mystery Shopping, but you'd like Merchandising, or constructing movie theater displays. There are lots of different types of jobs: way more than I ever imagined when I first joined this forum. Good luck!
