The company lists available opportunities and you apply for a job.
First of all, I recommend lowering your rates. Look at how much experience you have tutoring, and google common rates for tutors in your area. Secondly, messaging someone every day will likely just annoy them. Send the initial application, follow up about 48 hours later if you haven't hear anything and the job posting is still listed, but then leave it. Make sure your profile is polished and free of typos; I suggest you have someone skilled in resume-writing look over your applications. Write each application as if it were a cover letter. You want to look your best for potential students!
You are able to email and search through out the jobs listed that match your skills and criteria for each students needs.
If you are lucky and charge $10 then students come. Doesn't matter if you are qualified
