Discovery II - ABS, HDC, TC

Hi

I know this has been asked a few times before but I had a newsreader 
crisis the other day and lost all my offline news - and information 
through Google seems contradictory...

For a few days, the three lights (HDC, ABS and TC) would come on, along 
with the brake warning and chimes. After a restart, the fault would 
clear. This seems to get more frequent. Now, when the car is turned on, 
the lights all go out - except the ABS of course - and a moment later 
the three fault light come on but without any chiming.

Searching the 'net tells me it could be the sensor (probably front 
wheel), the wiring, the wheel bearings or the ABS modulator.

Are there other common causes? I will probably get an independant to 
read the fault codes but my faith is thin after I was once told that 
smoke from my freelander meant a new turbo when it actually just needed 
a couple of hoses.

Does the pattern of progressive fault point to anything in particular?

Can anyone indicate the likely costs of the various options and/or 
recommend someone close to south Stafford****re who will not want the 
blood of my first born and a share in my house to get the job done?

Most annoying is that only two weeks ago - before all this - I had 
decided to sell it. Now I may not be able to afford to fix it or sell it!
