You really, really should bring in a Realtor to help you:
You admit that you don't know what you are doing.
Do you have 15-20 signs to put out for the Open House?
Do you have a Flyer made up?
Did you do the Comp's to determine what the ideal Listing Price should be?
Do you have the forms ready in case a Buyer wants to make an offer?
Have you done your Disclosures?
Do you have the Hazard Report ready?
Do you know what Documents and Forms you will need?
Good luck and may God bless
