Thumbnail making for youtube channel

I’m looking for a freelancer to help create some thumbnails for my YouTube channel. I have a few ideas, but I need someone to bring these ideas to life. I’m looking for an illustrative style with bold, colorful images that will draw viewers’ attention. I will need no more than 5 thumbnails in total. I do not have any pre-made images or assets. If you think you can help, please reach out and let me know what you can do!
