Coaching packages

I keep going back and forth on whether I should be offering more coaching options to potential customers. I currently only have one offer for them : a coaching package of 3 months. I can’t seem to decide if it would be a good idea or not to also offer coaching “à la carte” or other coaching packages. I want to keep things simple, but at the same time I wonder if I am limiting myself and more money coming in, by only offering one option for working with me. What could help me get clear on what would be the best offerings for my business? Thanks!
