Booking enquiries plugin

Hi guys,
I’m looking for a booking site which can calculate dropdown fields (multiple choice), then e-mail myself and the customer a confirmation. At this point I will need to confirm with other band members their availability before the customer actually books (so essentially it’ll be a booking inquiry form at this point). I want a form which is customisable to reflect this. The form needs to allow customers to specify a start time and end time as well as date, band selection and optional extras. I’ve looked at plugins like bookly but it only has 1hr time slots… A new one I’ve just been looking at is Bookme and a new one developed this year called Calendarista which seems to be the most promising so far…

At a later date, I would like it to Sync to a Google Calendar and for customers to pay a deposit online at the time of booking (once the business takes off). Here I have an inquiry form https://www.empireband.com.au/bookingenquiries/ (currently visible to the public) and here is a price selection page https://www.empireband.com.au/prices/ (password is EMPIRE1212) which is my work in progress. I am currently using the ‘Calculated fields form’ but want to make sure I have the right one before spending $50 to access the e-mail information off and payment options, so am looking at all options and would really appreciate some help. ??

Does anyone know what plugin would be perfect for me?

Thanks so much
