I've helped several people with this type of dilemma. The first option is to agree to a contract and ask for installments for payment. Most companies understand you need capital to conduct your operation and will agree to give you a portion up front. Option 2 would be to secure an LOI and seek either a high net worth individual or someone willing to provide contract financing. Contract financing can get extremely costly and I would view it as a "last ditch" effort. My recommendation is to push for an installment. Hope this is helpful, best of luck.
