Drupal reservation time slot and Joinable feature extra code

Hi, We finished this feature , but I need to add some extra code to make filter based on Date Location Time So when you select date , you will need to select Location , and then it will show you the Time available. The old project and its already done : I need someone good with Drupal and he know how to program .. I am front-end developer and I work with Drupal as well. Progress will be like this: DONT BID IF YOU DONT ACCEPT THIS: 1. I will provide the full site code for you . 2. you make the change and show me how it works and login for that and test it 3. after everything is good . I will make milestones 4. you deliver the code and everything 5. I release the milestones. I have restaurant reservation Drupal distribution I change it to make it for another booking service.. and I need to make some features. as following: Here what we need: 1. I have these fields: Date ( date field ) Time ( Select list ) 1|08.30-10.00 2|10.00-11.30 3|11.30-01.00 4|02.00-03.30 5|03.30-05.00 6|05.30-07.00 7|07.30-09.00 8|09.00-10.30 Status ( Select list) pending|Pending confirmed|Confirmed cancelled|Cancelled The thing we need to make the time not selectable (grey color) if that node with that date and time already exist and the status is confirmed. ___________________________________________________________________ 2. We have these fields in the booking form: Person: ( input field) We need to add new field as checkbox or select list ( Joinable ) , And if someone (xxx) booking for 6 persons , and make that booking Joinable , and we make that booking confirmed , then the booking still showen in the site with color (green) for specific date and time , and will be allowed for another ppl (yyy) to join that booking. and It will be one only then the booking will not be selectable ( time and date) if we make that confirmed. I hope everything is clear for both features.... Some pictures attached. Regards
