Could anybody recommend me a garage in South Wales?

Hey lads, sorry if this is the wrong forum. im living in Cardiff Area and i just got told i need the following work done

Replace nearside front track rod end and stg arm
*nearside track rod end worn to excess
*excessive play in near side steering arm


Replace nearside front suspension arm
*n/s front sus arm rear bush split

Not sure if these will cause a mot to fail but better safe than sorry and Im having trouble finding a garage to do the work for me, first garage ordered the wrong parts, saying i need specialist parts or whatever and another garage told me id need to replace the whole steering column?so im getting stressed out. Does anybody know for a good garage in south wales area by any chance? cheers lads.
