You're not getting free designs from any Pro. They will consult with you, show you a portfolio, and develop a rough concept. You don't get a copy of any of that. They own their intellectual property. Then if you want to move forward with design development, you will need to pay. Then you will receive copies of the designs, and work together to tweak them.

Thank you! I know I won't keep a copy of anything but is it customary to pay for consultations and how can price me for something that hasn't been designed? I couldn't possibly decide to move forward without seeing potential plans for project. I guess it's how landscape design works??

It is how many designers or contractors work. You would be receiving custom work, tailored to your taste. It's the difference between a generic $3 Mickey D's hamburger and a $40 hand cut steak cooked to order just as you specify.
