Up front capital invested can range from as low as $500 for a small, shallow pond aeration system to as much as $8,000 or more for a larger system or a solar aerator.Operating cost is dependent on the number of amps needed to power an electric motor multiplied by the electricity cost in your area.ome electric aerators might run for 2-3 years without any major issues and others might run 5-7 years or longer. The table below is based on a set of assumptions that is fairly representative of actual costs for a 1 to 2 acre pond or small lake.
Surface Hub costs less than half that, and is in essence a collaborative center in a box. Costs for a conference room that would accommodate the lower-end unit are about $6,500 to $27,000, again not including furniture, installation, service, and ongoing management costs, so a similar savings can be had there as well.

Mako Steel estimates the most high-end self storage facilities have somewhere between 60,000 and 80,000 rentable square feet, and costs $45 to $65 on construction per square foot. The cost of construction will also depend on the unit's amenities, such as if the unit is climate controlled.
