Let us first discuss the size of the studio you will need the most probable. In general, a piece that is longer than wide is perform better control with ambient lighting and your artificial studio lighting, such as umbrellas and soft boxes.
I recommend a minimum of 10-12 between the photographer and the subject. Also allowing room for air circulation will keep your comfortable topics.

This goes for your muslin backdrop is, umbrellas and electricity bills and rent. If possible, I recommend trying to find a new warehouse to rent for your studio. Most warehouses have a small section which can be rented for about 5-15 $ / square foot depending on location and rent.
Realistic goals and timelines
I recommend taking your objectives and deadlines and extended by third parties. I say this because most things are beyond your control. You cannot control the duration of a lease is to create or shipment of products for you.
