What is acceptable to put as my availability?

Because of some things that have come up, Im kinda forced to only worked mon/tues (5-930) and limited hours sat/sun. I would still be able to make 12hr/week but it would look like: mon/tues (5pm-930pm) sat/sun (7am-2pm), is this acceptable or should I give up on this job because I don't have time for it? Please be honest.
