I'm charging £50 for these as its a little bit out my way, I told the customer that perhaps they will get it cheaper if they found someone more local, (to be fair I'm only 10 miles away, but that's far for my round lol) Anyway they were happy with the quote, to my surprise, so I'm going to do them on Saturday, I'll need to take my time as they take minutes to clean, it's embarrassing charging that much for a small easy job!? But I didn't think they'd except the quote! There not a customer of mine, but rung me purely to have this done, so maybe there desperate, What would you guys charge for these to be cleaned? Normally I'd probably charge 30-40.. Perhaps £50 is fair enough? Just seems a lot of money for an easy job? I shouldn't complain, but I don't lole to rip people off! Maybe I'm being to kind, if there balky with the quote then I shouldn't feel bad...?!
