Good Afternoon!
While I am a freelancer, I am also a UI/UX full time designer at a mobile app agency, so this project is right up my alley. I am comfortable in using any specific software you may need. To start a project, I like to ask a couple questions to get a good idea on direction for the project. What is the main functionality or purpose of the application? How many pages/screens are you thinking you would need for the application? I understand you have a logo, do you have a color or colors you want to incorporate? If you have any app inspiration you want to share, that is always a great starting point!
The reason I went slightly over on my bid is because typically it will take roughly 30-60 min per screen depending on edits. I would love to talk more about the project! Thanks.
