Hello and welcome Carmen, nice to have you here
This site is full of great advice for getting your business running and keeping it busy with happy clients. I'd stay start at the top, take lots of notes, and ask plenty of questions as you run across topics that seem confusing or you need more information on.
You're in great company and there are always amazing VAs here to help answer questions and give encouragement.
Wishing you the best of luck in reaching your business goals!
