What software (software) to use for scheduling?

Question

Time Management

It is necessary to draw up a schedule for internal use in a social organization. service

1. Entities - employee (who leads the class)
   
2. Occupation (for example - adaptive physical culture or psychologist)
   
3. Client - full name
   
4. Timeslot(?) - the time for which the client is registered on a specific day of the week
   
5. Classes can be shared - for adults, for children
   
6. The lesson can be individual or group - when a group reaches a certain number of people, it is no longer possible to enroll a person in it
   

Schedule - weekly
Duration of classes - varies from 30 minutes to an hour - randomly.
As a result, it should be possible to:
generate a general schedule for all specialists and classes (and filter free places from it - with specialists, by time, by date)
register a new client for free places - by selecting certain classes / specialists / days of the week
, create a schedule for a specialist
create a schedule for the client (optional)
quickly remove the client from the schedule (optional)
Specialists - about 14 people, about 30 classes, clients - up to 300 people.
An important point - for each specialist - per day, for example, 8 hours of classes or 16 half-hours. That is, it can be reduced to a free table only for sorting
software that is googled, basically it doesn’t look like it and is very expensive. It seems like Bitrix24 allows you to create this through booking, it turns each client through a deal + a lot of money. Can this be done in excel or google sheets? Broke my whole head
