Hard to schedule a time, how to respond?

Cold approached a chick at a department store, talked for a few minutes and got her number. Soft closed but she says she is “busy” for the whole week and weekend and won’t find out her work schedule until next week. Was considering responding with “Busy girl. Look, I’ve got shit to do as well. But I’m sure we could both find a few hours if we actually wanted to.” or “Busy girl. I’ll check up with you next week about your new work times” or "Busy girl. Let me know next week when you get your new work times", but the first one seems too soon, the second one sounds a bit lame and the third one seems too passive if I'm waiting on her to follow up. What do you suggest?
