Sounds like you have covered all the bases frobn.
With your programming expertise and Jared’s design capabilities I’m sure you will develop a formidable system.
Your biggest obstacle is overcoming the negative connotations associated with real estate template sites IMHO however, forums such as this is a good start.
We can further promote your system by implementing the “Work For Hire” categories you proposed and was discussed
here.
I hope other REALTORS® will participate in this thread with some useful feedback.
