Can anyone provide me with a notice to vacate for my tenants?

[Tim Ball]

I need to give an official 30-day notice to my tenants to vacate so I can have it in writing in the chance that I have to evict after the 30 days.  I really need to give this to my tenants tomorrow, Monday Aug 1st.  Can someone please send me what they use?  Thank you so much.  Also, in that 30 day notice to vacate form, can I mention if they are not out after the 30 days that the eviction process will begin?  Thanks for the help
