I think you can negotiate with each other and let them invest in the form of secured loans or mortgage loans. In other words, with your store as collateral, you can repay the principal within a certain period of time. If not, it can be returned in the form of increased share capital. In other words, if you can't give the other party the principal at that time, you can let the other party get more shares. Until the principal is recovered.
Finally, I want to say that others will invest, definitely for profit, but there is no free lunch for you. To get this investment, you must pay a certain price. Think about your tolerance before you make a decision. If it really doesn't work, you can borrow money yourself.
