I do not normally do this, but necessity trumps pride at the moment...please help if you can

I'm in a bit of a bind because closing is going to come before I get my tax refund.  I have been approved to build a home through the USDA's Rural Development Self-Help Program.  The down payment is covered through sweat equity.  Unfortunately, the Builders' Risk Policy is not and has to be paid for before closing.  I'm a single mother, with 2 kids at home and have worked so hard to fix my credit and get on the right track.  Please help us to make this happen.  You can donate by going to https://fundly.com/users/471455
