As above- but if you want some free non-confrontational advice- I'd say just start small and play with a bit of your own money first and see how you get on. It's a minefield this game and I wouldn't recommend that anyone gets into it nowadays AT ALL. It's much more hassle/complication than some think.
Getting the stock, preparing it, selling it etc is all very difficult and that's without the sales process, punters, recon, costs, VAT, CRA etc.
Good luck though and there's loads of similar threads on here that I'd suggest you spend a day or so reading. All very helpful and it saves you and Mrs. Maybe or whatever he's calling himself today falling out ;0) However he's maybe a bit 'fruity' for some but speaks the truth.
