Want to add custom booking system on my wordpress webpage

Hi, I have travel webpage,

So I want to add custom booking system,

So, what I want,

Customer should be able to choose your himself, I have premade tours, then when they click next, they should choose hotel for each stay, after that any addition packages, which I will be able to add.

and finally I want, they should be able to create custom tours themselfs, where they would choose cities, and script will tell it itself how much it will cost.

Payment method will be mine, bt once he will finish there should be an option to pay for that.

Let me know rates and timeframes.

I can do this
