Web Designer Familiar with Squarespace

My company is looking for someone who is a capable designer who has built Squarespace websites.
I need someone who is excellent at design who has worked in Squarespace.
You must have the ability to take my website requirements to deliver a mockup from your own creativity and move on to building the sites with my team's guidance.

This will start as a freelance or part-time position while moving to a full-time position down the road.

Thanks!
