Do you like dogs? There seems to be a market for dog sitting in your own home. Some dog owners prefer their pooches to go somewhere homely rather than to a big kennels, or so I'm told. Or perhaps offer to take in small caged animals - rabbits, guinea pigs etc - while their owners are on holiday, even goldfish. The old marketing maxim is 'know your customers, know what they want and then give it to 'em'. A bit like Mr Dyson finding out that his target market (people who do the cleaning) don't like the cords on their vacuum cleaners so.......well, you know the rest! Good luck, I hope you find something.
