Seeking out Interest free loan 🥶

I was going to open up a Business on large scale, and all the Banks refused to loan out the money, saying the business needs to thrive for atleast 3 yrs before they can loan out the amount. Then I changed my plans to open on a smaller scale with own money, but the problem is the lands I own aren't selling at all for the last 2 weeks, and I am badly in need of cash. I am looking for 2-3 Million Pkr, and I also don't want to loan from Banks with Interest. Is there any Halal way to get loan from somewhere for 1-2 months? Till the time land sells, and then I can repay back.
