Rust!

[Bcivic18c]

Hello, im new to the forum. Certainly not new to honda... Long story short i have a civic eg hatch thats hidden a rusty dark side for a while until i stumbled across it, basically the drivers side (maybe tbe passengers too) rear arches and rocker panels (under sill) needs cutting out and replacing. My question is has anyone had any experiance with a garage performing this job? What did it cost? How many hours did it take? Ill upload some pictures soon as i can... But its bad! Any help will be appreciated cause im sat here pissed off and feeling sorry for my honda
