Not really, some of the PFA lot over here can give the pro engineers a run for there money on quality and knowledge.
Reading the advert again I can spot the spelling mistakes, didn't the first time. Maybe the seller is also a degree qualified dyslexic Mechanical Engineer who has been taking stuff to pieces and putting it back together since he was a nipper like myself.
Doing a 50 hour isn't mensa material and neither is doing an engine change to someone that has an engineers head on them. Crap spelling and grammar in my experence doesn't effect the quality of the job at all. None of the machinery I have worked on be it earth mover, tank, lorry, aircraft, car, pumps, compressors or for that matter washing machines have suffered due to my crap spelling and grammar. Although to be fair some of it has suffered getting beaten into submission with a sodding great hammer or a 6ft lever bar.
