Their website isn't too helpful. From what I can tell, you can request a postponement by sending in the questionnaire - where I live you can do all this online. Tell them what you told us and do it ASAP so you can get a quick answer. Also be aware that unless they pick you the first day, you'll have to call once or twice each day for a week to find out if they need you later that day or the next one. The last time my wife got call-in jury service, when the days came, she forgot all about calling them. We never heard from them again.
