Web App UX Designer

We are creating a crowdfunding site like Kickstarter, but for films. We worked with a design agency over the last month and finished about 80% of the UX wireframes. We need help finishing the remaining UX designs. We are looking for a UX designer to join us on a video call for 1-2 hours every day for the next two weeks, screenshare the Figma file, and complete the UX designs with us. Please provide examples of past web app UX design experience.
