I think its a reasonable idea but are going to do face to face or zoom type consulting because if it's face to face that could get expensive for you travelling every where but you won't get the feel for the customer on zoom but my biggest worry would be the sue the arse off you mentality of most folk who decide you have given them the wrong advice or think your on a back hander from the dealer you have recommended because, let's say you get them a van that's totally damp free with a good hab check history and for arguments sake it's £30k but Mr customer has seen the exact same van for sale on EBay with no hab check and to en experienced owner an obvious damp issue but it's £25k it won't take long to get a bad reputation but that's just my take on it
