How do you make a ballot initiative in US states?

Question

The following US states allow statutes to be passed by "initiative":
AZ, AR, CA, CO, ID, MO, MT, NE, ND, OK, OR, SD, UT, WA.
The following US states allow constitutional amendments to be passed by "initiative":
AZ, AR, CA, CO, FL, IL, MI, MO, MT, NE, NV, ND, OH, OK, OR, SD.
I want to know the procedure - who to contact, who to pay, what amount to pay, what requirements you need etc, to get a ballot initiative going in each of these states. (May be a different answer for each; this is probably too much work for any single
answerer to answer in full, but may be easy for just one state.)

The following sites answers your question to exact detail:
http://www.ss.ca.gov/elections/elections_h.htm
http://www.ss.ca.gov/elections/elections_initiatives.htm

Typically the authority in charge of elections, voting, and ballot measures is the Secretary of State of the specific state. The above info is for California. If you go to the website of the secretary of state for your state of interest you can find this same information. This is public information that by law has to be disclosed to anyone who asks for it. If the site doesn't have it calle them and ask them to mail it or email it to you.
