• Stay humble. If you just started learning there are likely many things you haven't yet discovered/understood. Bitcoin is a long term journey and there is a lot of noise that takes many years to comprehend and filter out.
• Onboard as many people into self custody as possible
• Give them and educate them on correct usage of the tools, specifically securing keys, etc.
• For people that are filing capital gains (their choice, I know DarthCoin will explain otherwise), show them non-custodial and local tools for how to generate LIFO/FIFO from their transactions (i.e. please don't push them into using some monstr privacy destroying online service that asks you to upload all transactions)
• Get solid lists of opportunities where to actually use and spend bitcoin
• Have a well tailored list of materials for each person (e.g. someone may like to read interesting book that you would suggest like Mandibles, Blocksize Wars...)
• By yourself actually learn how to act online fully privately and anonymously. I would suggest you try getting yourself familiar with darknet markets and go through the tutorials about how to use those. I'd expect my financial advisor to have solid set up in terms of privacy and anonymity (e.g. I'd expect you communicate with clients over Signal, use non-Gmail like proton, etc)

I think one time fee for initial set up and then hourly fee for support would be reasonable. There may be some power in in person support.
With Bitcoin the trust building is even more important, so you need to give a great deal of verifiable visibility into what you are doing.
