2001 ford mondeo 20 tdci 130 bhp - can any1 help lease - nibbo

hope some1 can help . i am a single dad out of work , i bought a mondeo tdci 6 weeks ago , everything been fine , but this past week everytime i dip the clutch (but only when car is moving) it makes a wurring noise, i dont have any clunks or bangs coming from flywheel, , tho as i am out of work i really cant afford a flywheel change ect, does any1 know of this sort of problem an will a clutch an slave cylinder fix it? as i been quoted £650 to do it all with flywheel , but really dont think i need flywheel doing yet . thanks guys
