Assistance starting a home-care business

I am doing many new things now that I wasn’t doing a year ago, so I imagine your role might evolve as well. Here are some things I know I would like to entrust you with managing right away:
Managing my agenda as a gatekeeper against any waste of time
Booking professional and personal travel
Making sure all expenses are properly recorded

Coordinating lunches and dinners with my senior team, key customers and partners, and other constituents
Collecting and driving a list of key decisions I need to make each day, such as: things I need to sign, documents to review, important emails, invitations, deadlines, reminders, etc.
Coordinating events in the office where I am hosting including startup poker, monthly community happy hours, recruiting meet and greets
Taking on random tasks that are important to me but difficult to complete in between a day fully booked with meetings
