Wrong conclusion. Local soldering guy could do the same common mistakes. If you really have to use services then send it to one of guys that advertise their services here, since they have more experience with that installation. But then if you have some guts, just do it by yourself - it is fun experience. Just have good research before starting and follow Sthetix video preferably. His advice was to use polymide tape to protect fragile parts of board from surges and be generous with isopropyl alcohol when cleaning bits of glue and thermal compounds. I followed his guide fanatically and it was my first time soldering such small components. It was a complete success.
