Growing Medication In Michigan- Legal Considerations

My friend and I are caregivers that are growing for our patients and ourselves. We are looking to move into a warehouse to expand our grow operations because the house we are using is too small. We want to begin to include other caregivers in our new warehouse to grow for there patients. Our goal is to create a collaborative of caregivers to reduce costs of growing and increase the quality of our crop. We plan on incorporating (registering with the state as Inc. or LLC.) the grow operations as a business.

Issues:

1. Is it legal to have a large-scale grow operation where caregivers all grow in one secured, locked facility (growing the state legal limit of plants per patient)? Or do you need to have an address for each grower?

2. If we want to incorporate ourselves and register with the state, what do we need to consider, be careful of, etc.?

*3. What lawyers can I speak to, that can help me in the process of establishing a business growing medical marijuana for its patients (given that the federal government classifies marijuana as illegal)?

*As a business we would need to get a tax ID and pay state and federal taxes which is an issue because the federal government has not legalized pot.

Yes you can have a co-op in the State of Michigan. If you are serious and looking for reliable, factual information the KACC (Kalamazoo Area Compassion Club) meets the 2nd and 4th Tuesday of every month. They are a non profit group with both caregivers and patients as members. They have both a Doctor and a Lawyer that sits on the acting board that would be more than willing to answer all your questions and assist with keeping you on a legal, albeit discreet path.
They have a web page where you can find contact numbers and directions.
