JQuery Datepicker search

I hope you can help me.
I'm looking for a "special" JS / jQuery Datepicker that needs some special options:

I'll try to explain it to you with jQuery UI Datepicker
- same function as Inline Datepicker
- 2 Datepickers should be shown at the same time

- It should be possible to disable Dates !! !!!!!!!!! (thats Problem why I am not using jQuery UI Datepicker!)

Can someone give me a good hint?

thanks and have a good weekend.
