Hi CD's

I want to pursue my career in Mortgage. I am currently in job and want to opt as a Part Time career in the beginning. Can u please advise me how to pursue this as a Career. What is the scope of this in Future??
Where should i join the course from?
What is the duration?
Once I get the license how should i proceed in the market , Do I need to join some mortgage professional who's already in the business?

Thanks
