First God Bless you. We seem to have become a throw away society. It is hard on the young and old.
In any event, ever heard careful what you ask for.......?
Call the local Parks and recreation Departments. They often are responsible for both groups. (young and elderly) then contact churches and ask to make an appointment. Develop an honest brochure of what you intend to do. Now this is the tricky part, you will have the very best intentions but really how many clients can you PERSONALLY be responsible for ?
When you decide that, make your appointments and sell your services.
As you grow and you will, in leaps and bounds, you will be at the mercy of the help you provide. Start slow and charge accordingly. Good, honest, loving, help, to watch the dearest of our society, is worth more than anyone can pay. So set your prices and go to work. You will be tempted to try to do more.
That's when you will find that not everyone is representing you, Your name, morals and good intentions. Be careful there!!!! and again thanks again and best of luck.
