What do I do with my script?

I'd post this elsewhere but can't think of a better place.

I completed a script for a science fantasy comic, one chapter/issue of a bigger story, and I am looking to beat it into better shape.

The problem is that I don't know how and where to post it on this site,

I'd have just uploaded it to my portfolio but it's not in the state that works are to be in when added to the port folio.

 

What would be the format?

Should I just post one page at a time or is there someone to post the file?
