Hi Coling
Sorry things have stopped working for you, and you're obviously very despondent at the moment. Maybe just take a step back and give it a rest for a short period and then come back again with a fresh mind. There's more than one way to skin a cat, and maybe what you've done in the horse markets could be applied to other ones with just a few tweaks?
It seems silly that all your experience and what you've learnt goes to waste, and keeping going even in test mode trying new variations might yield a whole new approach.
Whatever you decide, good luck.
