I am just throwing gum against the wall to see if it sticks...
-the easy thing to try is your own website..costs and how many people will find you is hard for me to determine
-network with other small home based candy makers and pool your resources
-find a local manager of a store or a chain (doubt if chain manager can allow you to do it) and have them offer your product
-contact your state representative and ask what programs the feds and state have to help you set up business
-contact a local college or university...often their economical depts. have programs to help local business or perhaps you could contract with their food service to provide treats for special functions and events, just a start, but every dime in the kitty feeds the cat
-contact local charities, churches, etc. and offer them candies for fund-raising
you can think big and keep it simple, or think simple and let it grow big.
I'm sorry I haven't got a magic bullet, just a few ideas in a few seconds.
Take care, and prosper
