Hello! My name is Adam, I'm a Unity developer of 3 years, and I can certainly get this finished for you, today,
The UI fix shouldn't take more than 30 minutes, and the claw maybe 2 hours. If you have something else really small to add in, just let me know (changing font, etc) and I wont charge an extra hour for a few minutes of work.
Otherwise just let me know if you have any questions and I'll get this done today for you,
Adam
