funds for family consumption (until end of january)

I had a fishing business which i sold last november, we had a deal with the buyer to pay the agreed amount in two. the first one would be on the day of agreement, and the second would be on december. we both agreed, i recieved the haf of the money and spend it all on necessities. but by December when i asked him of the remaining balance he asked me a favor to delay the payment because he is still waiting for her wife who just came back to US (working as a nurse) for the money because he cant provide it himself because the boat he purchased from me is still under general repair and is not yet generating income as of now. i double checked all his statements and situation and confirmed it. i also talked to her wife and she promised me to send the promised amount by last week of january. so as considerable as i am i agreed. and now the problem is i dont have any funding for my family's daily expenses. i looked everywhere but nobody seems to care at all. i have also engaged into multiple online loans but they have very minimal amounts (500-2000) to lend me. resulting me to apply in many online apps. and it is not enough since i have only had 3 successful applications amounting to a total of 5000 only. and i am very sure it wont be enough until the last week of january. so i am asking a favor to anyone who can help me with my case. interests would be applied. and I promise to return back any amount of money you can lend me by the end of january or anytime we could agree or even in installment or in any way favorable to the lender. if you need any details or proofs please dont hesitate to contact me thru email. please contact me thru email as i am more accessible online than in phone. but if phone is preferred please send me a text message so that i can call since i rarely check my phone let me be the one to call. thanks and God bless!
