Multistep form

Hello
I need to do a multistep form with some specials conditions:

1. I need to be able to choose the recipient of my message (in function of choice of a question into my form)
2. I need to be able to customize the customer email
3. I want to add some calendar to put date end and date start
4. In function of number of gap between start and end i need to be able to calculate price (it’s not required functionnality)
5. In function of choice of number of cats i need to have a duplication of a lines (like firstname / age…)

I would like to use contact form 7 by default if it’s possible ?

Thanks
