Don't know what you should charge but if you want to go under cover and pass yourself off as a Cabbie you'll probably need to gear yourself up with a Dastar like my Sikh mate Jatinder who lives up the road and around the corner a bit from here. He's not a Cabbie, not sure what he does actually, but he often jokes about how many Sydney Cabbies are Sikhs. Only problem is that you can't be seen drinking Beer if you're wearing a Dastar. Those boys, the true ones anyway, don't imbibe. Not a drop. Big-time Tea drinkers though.
