For the first page I would like to see a login page, something clean but also memorable and attractive. If there is a logo of the company on it, please do not cater it to the name of the site as that will probably change, but maybe something sports related.
For the second page, this one is a bit more complicated. I've included a really rough UX sketch I made on a whiteboard to help out. The idea is this is where the player will browse the map for various requests for players. Ideally, the map is themed, as is not the generic map colors you see on google maps. The page should allow you to filter requests for players, for things such as from date/time to date/time, sport, player level, and maybe an option to see currently booked requests, past requests, and open requests. The pins on the map that represent these states should be different.
Ideally, the overall page also should show the current user, maybe a dropdown on the right side for personal navigation (user profile, help, logout), and a main navigation on the right (find match, request player, my bookings, leaderboard, etc).
