I'm very experienced with making book covers and since I've taken the time off for writing, I would be more than welcomed to make a book cover for you or even a Book trailer.
Here's an example of a trailer I made:

Here's an example of some of my book covers (pictures DO NOT belong to me):

If you are interested, just give me a summary of your story and I'll get right back with you. I really like helping people with writing and so feel free to message me and ask for a Book trailer or book cover. :)
Thanks,
Tia W.
