Was wondering if someone can help as I'm at my wits end and about to cry

Our Bongo (V6 petrol) has started to smell of burning when driven - drives fine - just this smell. I have taken it to 3 garages so far and spent 2 weeks walking everywhere (at 5 months pregnant with a 2 1/2 toddler in tow this isn't always fun!) for each garage to tell me that they can't work on it or give me a proper diagnosis, whilst charging me greatly for their 'help'. The vague diagnosis I have been given is that there is an oil leak, probably from either the crank shaft seal or the cam shaft seal but no-one can get in to have a proper look.
Anyway - my question is, I have heared talk on here on a spreadsheet that exists listing 'Bongo firendly' garages - if anyone could point me in the direction of this I would appreciate it so much - I can finally take BongoGeorge somewhere he will be properly looked after.
Thanks in advance,
Chris.
