Custom Price for each service

Hi there,

First of all I wanna say, you're doing an awesome job. I really like your plugin and I don't wanna move to another service. which is why I am asking you for a new feature.

Is it possible if you can add a new feature where customer can customize price for each service or I can create a new booking page with a custom price specifically for that customer. and also I only want to use it to get payments, not the booking.
I have multiple clients and I want to send them a custom link where they can simply enter their personal details and then proceed to payment.
we can also do that like payments in milestones if that's possible. That'd be great.

Thanks
