Hi!
I relay like your project. unfortunately I've came across it today. I am afraid I wont have much time to pitch an interesting idea. sorry for that. Let me know if you could extend the deadline.
Thanks and Have a nice day!

-ps : if you are interested in extending the deadline, I think its best to design a logo first since it can shape your UI design.

this is an example of a UI/Logo design I've done. You can see I've used elements from the logo when designing wizard UI.

in the web page design for the same company Ive used same elements from the logo again to keep consistency.
