1) Child daycare. Each child you care for should amount to about $100 per week in income depending on where you live.
2) Doggy Daycare & Walking. Here in Seattle, people pay nearly as much to drop off their dogs for the day as they do their kids. What's really weird tho is that childcare workers make minimum wage-$7.75 per hour. Doggy Daycare workers and dog walkers make $15.00 per hour!
3) Sewing and mending services. People pay $2.00 to replace a jeans zipper and $4.00 to hem a pair of pants. A custom prom dress runs $200 and up.
4) Have bake sales. Cook up a bunch of goodies and then have a combo garage and bake sale. I always make more money on the baked goods than I do on the garage sale but people will not stop to look unless I call it a "Garage Sale." A dozen homemade cookies is $5.00 or more.
5) Grow plants and have periodic plant sales. I recently purchased 1 very over grown spider plant at a store and split it up into over 100 small plants. In the spring these will sell for around $2-5 apiece!
6) I do Ebay but in a rather unique way. All of the stuff I sell on Ebay I get for FREE. Examples are woodland ferns, native plants, Ivy, driftwood, etc. Take a walk with the kids and make it a treasure hunt. Stuff that are weeds and junk to me are exotic to people in New York!
7) Make jewelry out of beads and wire and put them on consignment at spas and jewelry stores.
8) Learn a skill like desktop publishing or transcription or web design. The more flexible and knowledgeable you get the more jobs you will get.
9) Schedule appointments for a local builder. Many companies need phone people to set up appointments for inspections, construction estimates, etc.
10) Figure out what you love to do and then work out a way to get paid for it. If you love soap operas, find someone to pay you to write about them. If you love crafts, make them and sell them!
