I am IRL a certified music teacher I can easily create a site that acts as a resource for teachers and students in every instrument. Have guest articles, a music teacher database by state and region and promote clickbank and amazon products. Even if I rank #1 for every possible keyword, do you think the effort and time creating a site like this will bring in enough money to make it worth it? What do you think a realistic monthy revenue for a site like this can be. Thank you.
