I think it would help potential cover creators/artists if you gave a little more info on what you are looking to get/hoping to get.
Think about the style you prefer
how many characters
maybe give some examples of covers you like
poses
etc.
So that the people seeing your post know what you would like.
And please know that making a cover can take hours if not days for some artists/creators, so a little gratitude and effort from your side is appreciated.
Credit is expected. Always. Unless the artist/creator tells you not to 
This is just meant as friendly advice, so you can get the help you are looking for
