@Rosa Aponte There are a few options, the first are the larger more general platforms, like UpWork and Fiverr.

See what platform has the most listings in your market and start there.You could be more scientific: I track each platform where I posts ads, so I know which produce the solid leads. 

I have exhausted my sphere of influence, I have written letters, passed out cards, and am active on social media platforms.

Do you have social media platforms?  

.- I'm a very quick learner and have worked with and have adequate knowledge of a variety of software that includes: Hubspot (CRM), DocuSign, MailChimp, Adobe Editor, Dropbox, MS Office, MS Project, both Windows and Mac platforms, etc.

After I found a tenant (via Zillow) I am using the Cozy platform for payments and such.

Try Rocketmortgage out - it offers the simplest platform to apply and complete a mortgage.  

I also only work on platforms that are self service, so you can maintain them without having to pay a developer every time you want to update pictures or small things.

You can even search different platforms like Zillow and Realtor to see how many sales an agent has completed in the past year.
