Well... I think that teaching English at home or through fun methods is always a good complement. If I were you I would go to Spanish Neighbours Associations, Women´s associations, or any other kind of clubs with a good proposal.
It is always good to work contacts ( network). And to show different, well-priced products. Try to get the personalised style and to really care about your clients... that will bring you lots of work but also great satisfaction and benefits.
Everything children oriented usually kicks in, but again, be proffessional and caring. Do not see the activity just through the market, making-money glasses because it will lose interest, strength and success.
