But I also like to see other entrepreneurs and companies, those in our industry and even those outside of it, who are thriving and not only helping the city, but also helping real estate investors.

In Ontario, Canada, we must adhere to REBBA (the Real Estate and Business Brokers Act), which does not allow some entrepreneurs to be quite as creative in their negotiations, financing, etc.From what you have described of your situation and your goals, it seems best for you to learn what you can from the course and materials, but to not actually become licensed.Another option is to take the exam(s), but not apply for your license.

I am curious to see how much a rental owner would pay for a service that would help them advertise their business, possibly run their social media and fill vacancies at the same.

You can find a bunch in this site.Just be weary as to who you trust as BP does not monitor who uses this site as it is a social networking site.

Market it all over social media, pound the pavement etc.
