How do i contact schools and etc to speak as a motivational speaker
You need some credentials - usually publishing a book that lots of people buy. Schools (particularly non universities) don't usually bring in motivational speakers.
Call them and tell them the subject content and fax them a copy of your brief history, summary of topic and experience about the topic. Leave your number on the fax and they will contact you if they are interested. Keep in mind, a lot of school are under school improvement under No Child Left Behind and there isn't a lot of time for these kinds of things so unless it relates to school somehow in a subject area they will tell you no and don't be disappointed if they say so. Private schools get no federal funds so their curriculum is more flexible and you'd still need a subject that pertains to educational purposes. However Private schools will give you better shot at speaking.
