Quoted from xTheBlackKnightx:People need to understand, the repair of surface mounted electronics requires special skills, tools, and equipment. The equipment is EXPENSIVE. The experience is not something you are going to "pick up and do" after 6 months.
Working with surface mount parts is really not that complex and expensive.
You will need a hot air rework station. These are available for very little on ebay or aliexpress (keyword=858D ), and will cost less than what you pay for a new flipper mech.
