Interview several brokers until you find one you like, that offers excellent training and support, has a congenial atmosphere, and a record of success - plus a good reputation. Ask what they pay for and what you will have to pay for.
Then, get out there! Let everybody you know hear that you are in real estate now - shout it to the skies, email and snail mail everybody with your new business card, send out marketing materials and advertise yourself.
Create a business plan and work your business plan. Ask your broker for help developing one, or go to a SCORE volunteer.
As a newbie, look for a mentor in your office. Ask to ride along on showings and watch closings. Offer to sit open houses, for exposure.
You could be a loan officer, but I think that requires a different set of skills and experience and training - and could be a conflict of interest to your potential real estate clients, so be careful.
I don't see how you can effectively pursue 2 new careers at the same time - invest your time and energy into just 1, and strive to succeed at that one.
Good luck and best wishes.
