Help me find a plugin for a specific purpose

I’m trying to find a plugin or multiple plugins that will do the following:

1) A business can log in and put different information in everyday of the week.

2) A visitor to the website can see the information that the business owners put in for that day.

3) The visitor can select businesses that have that information from a google map.

so basically a business owner can log in, put information on a calendar and on that day of the week a visitor to the website can see the information that the business owner put on the calendar about their business. So if Bob’s frisbee shop sells red frisbees on monday and green frisbees on tuesday, a person can see on Monday that Bob has red frisbees. I hope this makes sense and thank you in advance for any suggestions and help.
