Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
I am GMT + 12, so 10am for you is 3am for me. That is not going to be possible. Saturdays (Friday night for you) are the best times for me. Or my Thursday or Sunday evenings, but that may involve quite a late night for you (IE after midnight).
