Vela Luka Ferry sailing schedules for April

We are on holidays in Croatia in next April and we would like to have some information on sailing schedules and prices for the following trip.

Please note that we will have a car, so we will need a car ferry.

Split => Stari Grad (Sunday april 8th in the afternoon) => Vela Luka (Wednesday april 11th in the morning) => Dubrovnik (from Korcula? on Thursday 12th in the late afternoon)

I thank you for your help in advance
