Too many event types

HALP!  I am a Renovation Building and Interior Designer, Project Manager, Consultant and Coach.  My business has multiple service types and I suspect I may have over-complicated this with far too many service types in Calendly. 

I meet people both virtually and in-person.  I charge fees for some things and not others, but need the option to waive the fee at times.  I provide full service design, on-call renovation consultation services, and I also provide coaching and consulting for industry professionals. 

I would LOVE some ideas and feedback on how I can consolidate and/or simplify.  I have tried to manage this with the routing function.  The feedback I’ve received from people is they found the number of options confusing.  On my end, the routing link breaks far too often when I make the slightest change to any event type, then I forget to update the new routing link in all the places (email signature, Slack channel, website, etc...)
