Honestly, that's a lot to ask of someone to serve to you for an hour so you can practice your returns. My shoulder and quads hurt just thinking about that. How about you each serve a hopper and then switch back and forth so you each get a chance to work on serves and returns. Mix in some points/games to your practice too.
