Asking others to design a character for you is a dangerous move, especially since you provide very little detail. Creating a character can be an intimate, difficult process - it's not as simple as jotting down a few facts about them before slapping a name and random background on them. They aren't a faceless object whose only purpose is to play their role: they are a unique person with strengths, flaws, worries, and quirks that set them apart from others. You're forming an entirely new being, which requires you to look closely at their different aspects. For instance, their past is extremely important, as it influences their traits and helps form the person they are today. Their appearance is also essential, as humans have unique appearances with different features that help them stand out.
Because your character will also play a major role in your story, it's best to know them as well as possible so that you aren't constantly questioning what they'd do in different situations. Designing your own character will allow you to share a deep connection with them. Because you know them inside and out, you'll have an easier time writing about them than you would if it were someone else's character. They will fit better in your world and story. Furthermore, you are more familiar with your own plot than we are. You should be able to tell what types of people would be best fit in your world. If you truly value your work, you'll be willing to make time to create your own characters rather than asking other people to do so for you. You're more than welcome to ask for suggestions though. Best wishes.
