Hi I would like to have a admin guide if possible

Please do not ask for help to be delivered outside the Forums. The Forums are not intended to be used for private answers -- this is a community effort. All support should be openly available for others to lea from. Further, it is very unwise indeed to use your email openly as you did. Web crawlers scrub this site continuously. Some people with ill intent would probably love to have your email address.

After a few questions about exactly what you mean by your request, I expect that many suggestions will be posted here.
