Starting a Retail Business

[Michael Mastantuono]

hello, 

I am intent on starting a non profit 2nd store, something like the Discovery Center.

After talking with a commercial real estate agent, he has informed me I need to come up with a well detailed business plan to pitch to the prospective land lord. 

Honestly, I have years of retail experience and have worked closely with managers at donation centers, but putting together a business plan seems overwhelming. 

Any suggestions for online training or where how I might go about understanding what is really being asked? 

thanks. 

Any guidance would be much appreciated.
