A Cold storage Setup Looking for Funds

We want to open a cold storage unit. We have 2 options to run the cold storage option -1 A 5000 MT cold storage is established and run on a rental model .Which means farmers/ traders can store their produce mainly potato. In such a situation, 100% capacity utilization is not possible though the potato producers would be benefited. Because, the local produce if stored on rental basis may be taken out any time within 7 – 8 months. But remaining period of the year, the space will be unutilized whereas the electricity charges and manpower cost etc., is to be met for the whole year. Which means the rental earning of 7-8 months will be utilized for maintaining the cold store for the whole year.Option-2: A 5000 MT cold storage is established and run on a combined model of rental and trading. This means certain percent of storage space will be used as rental where as remaining space can be utilized by promoter to store potato by way of procuring at reasonable price during harvest period and selling out beyond the season at a higher price. This option is therefore more attractive proposition than the previous one.
