Frontend UX Designer with a great vision needed

I am developing a new web/dAPP however being a backend developer I am not the best when it comes to choosing fronts and color schemes. I am looking for a VERY experienced UX designer that can help me pick a nice (or improve upon existing) color scheme, and related fonts / font sizes and font variations.

Please only apply if you have something previous UX work to showcase.

Thank you.
