Where to look to sell your coworking space or look for investors (South Africa)

Hi

I own and manage a coworking business in Johannesburg which has been trading for 2 years and has built up a solid brand and reputation. I am currently looking at a few options going forward. 1. Selling the brand and the business model built up over the last 2 years. 2. Getting investors/partners involved to help expand and grow the brand and business. There is also the option to currently buy the building I am renting and get into property development and coworking as a whole in the area and thus landlord buys into business or takes it over?

Where does one go looking for these such investors or interested parties?

Thanks in advance
