Is An Agent Needed?

Hey everyone!
I hope I am not breaking any etiquette rules by posting here, but I would greatly appreciate your help. I've been juggling around the idea of paying an agent to represent me, but I figured that I would solicit your advice prior to doing so. I imagine many of you have some great life experiences to share with me before I take the leap of faith and provide another being with money to hustle for me.
Any and all advice would be appreciated. But, to keep the discussion focused, it may be helpful to focus on the following questions:
1. Do I really need an agent nowadays to market myself? If not, how do I go about securing gigs and, hopefully one day, promotions?
2. How large of a following do I need before securing an agent makes sense?
Thank you so much for all your help.
