Well, I can only draw stick figures. But I do have some experience with writing. I could help with writing the plot/story etc. Provided that you are able to find an artist that will work. It isn't easy to do art and it takes a lot of dedicated work to make art that looks professional. If you don't pay them, then they will not feel they have a good motivation for all the effort it requires to make the art.
That being said, I cannot draw anything but stick figures, unless I dedicate my time to it. Time I would rather spend honing my writing skills.
So what I decided to was to make Novels instead of Comics or Graphic Novels. As for the Thumbnails for the Series and Episodes, I decided to use Canva for royalty free custom covers, and thumbnails.
Sure it won't look pretty, but if the story is good, the art won't matter as much.
One day I will find someone who appreciates my stories and by then hopefully I will have the money from my Novels to afford an Illustrator/Artist.
As a Writer, there are plenty of Writing Contests in order to win some money here and there. It takes time and practice but you can win some money and be able to afford an Artist eventually.
Basically, Art and Writing takes a lot of time to master and to produce good results. If you don't pay them what the art is worth, then you will have a hard time finding any artist, and are only able to rely on luck.
I also offer my services as a writer for free in order to hone my writing skills and make friends. I help people flesh out their story ideas for free. That is also a great way to make friends.
Anyway, I hope we find an Artist. But I suggest using the money you make from acting, singing, and writing in order to pay for the art you need. I am rooting for you!
That is all.
