You are looking for more of a hybrid school or a place that offers classes for homeschool students. Co-ops don't usually pay the teachers.
I am a former teacher who now teaches homeschool students. I started with a group of 13 in my home. I have taught classes out of my home for 10 years. I have also taught at the local art center where I started a homeschool enrichment program (and was later recognized by the county for such efforts as it 'saved' the center in terms of staying open), a local church, an afterschool program, and a hybrid program.
Currently, I teach at a hybrid school two days a week and once a week in my home or at a local coffee shop. I tutor a lot -7 - 10 hours a week on top of my teaching! I spend my summers planning my lessons and writing my curriculum and maintaing my website. My income is greater than if I was teaching full-time - but - I have to pay for health insurance since both dh and I are self-employed so that is a factor now.
My advice is to build a reputation. You after-school your daughter so maybe start a bookclub or nature club or STEAM classes for girls her age. Invite her friends to join and then find homeschool kids to invite. People need to know you and trust you. Your reputation is everything when you are first starting out. Go to the community center and see if they offer anything for homeschoolers. Most homeschool families want science or foreign language for elementary age. Older students need help writing essays and advanced math as well as science. If you want to reach high school students offer required classes for graduation. Can you teach chemistry? Do you have the skills to run a dissection lab? If so, offer those. My science classes always fill up and receive high praise from parents and students who are grateful for the collabortive nature of the class.
If you want to get the top $$, go to the wealthy side of town. I live in the poor side of town, but I work in the wealthy side of town. I can charge double to triple what I would charge in my locale. (not sure if you live in a bigger city)
Give yourself time. I do not know much about the online market, but I would like to offer my classes online soon as I think that is the way to go.
