Can I upload portfolio template for sale?

Hello, I'm very new to codester or any online selling website as web developer. I have been working on creating a web portfolio template for creative careers like developer, artist, etc. I'm using HTML 5, Bootstrap 5, SCSS, and some Javascript. This is my first time to actually create any web template for general purpose and possible demands, so I want to make sure if my project will be acceptable on codester for sale when it's ready to be uploaded for quality check.

I see there are pretty many other portfolio template items already on sale here, and am not sure how long it will take for me to finish this template to fit your standard because I'm making it all from scratch with my own ideas. If you don't want to accept my item regardless of the quality match because you already have enough similar items, I would like to have recommendations for what templates or software scripts would be highly demanded. Thank you.
