Sadly going through the process of a divorce after discovering a string of infidelities

Please could people share how much their lawyers charged, is it based on an hourly rate?
There are no children involved but some assets, I would just like for someone to represent my interests

I've been recommended a lawyer by a friend and the charge is HKD 5500 per hour, which to me sounds extortionate and most likely out of my budget

Please could anyone recommend how much I should expect to pay or what the fee structure is normally like

Really appreciate any help
