submitting a plugin with two versions

Hi, I developed a plugin and it is ready to upload. There are two versions, Free and Paid. I want to submit it to the wordpress plugin directory. Do i submit it twice? Because i don’t really see anything on the submit page that helps me. Maybe i only submit the free version and place a link in the readme, pointing to the paid version.

This is my first wordpress plugin, so not sure how to go on about it
