Working real estate between purchases

[Collin Emerson Miller]

Hi all, I am currently in between transactions (just bought a place and now saving for next).  I was thinking of how to make some extra cash to save up faster for the next one.  I had an idea and would like to know the community feedback/response.  I have software skills (Artificial Intelligence, Machine Learning, Data Science, etc) and I was looking to leverage them to do some jobs for those who are looking for an extra data edge on their property analysis.  

I think that the idea is sound, the execution is the important part.  So my question to the community is, how do you think I should go about this?  

For finding jobs, I don't like the idea of cold outreach especially on BP (I am pretty sure that is banned/against TOS). I do know about Upwork/Fiverr/other contracting sites, and I have used them in the past (although they are pretty saturated TBH).  Is the way just simple networking and marketing?

For the actual content of the work, I can see data science/AI/ML coming in handy, but I am pretty sure most of the ideas I have already exist in some other software.  My question here is what kinds of jobs should I expect so I know what skills/showcase projects to have under my belt.

Thank you for your time and brainpower!
