Seven years ago while unemployed, I helped an elderly neighbour with her garden. While doing this I had several enquiries as to whether I did this for a living. Potential then.
Only way to really find out how to do something is go and do it.
I placed an advert in a newsagent window. 'Do you need help with your garden?'
That ad stayed three weeks. The following year the ad stayed just one week.
Never advertised since. Some of the early enquiries weren't too great but over time I've dropped the awkward customers and now only help out the one's I like.
Its a referral business, gardens. If you have the ability to drink tea and chat to old ladies then you're ok.
Mind you, I'm lucky I live in the suburbs. There's gardens everywhere.
