As an ex Management Consultant, Project Manager and Financial Modeler I have read this thread end to end. It has been fascinating (with the exception of Dapper Don who appears to have neurological problems or a personality disorder). The OP or anyone else planning setting up such a complex operation needs information, money, licencing, and project control. I can see why he is looking for ball-park information. Without this he cannot start planning. He really needs a qualified project manager BEFORE he starts, to anticipate the pit-falls and avoid them. His intial function is to refine the proposal. Without clear refined objectives it is more than likely to go tits up (large time and cost overuns until the money runs out). Design is critical and needs to be well costed and technically proven. Informal project management will not do at this level of complexity and cost.
When he has clarified his vision the project manager needs to schedule design, specification, licencing etc in time. This is a critical path function so that functions that can run in parallel do so, shortening the overall time between first spend and first revenue. Seems to me a flow-chart is needed together with a financial model, charting cash-flow on a month by month basis. This needs to be cleared with the backers. There needs to be regular reporting to teh Board/Backers matched against the critical path. If the OP (or others planning a similar operation) does not appreciate this, there will be tears! Remember - you cannot simply scale up a domestic grow. This is quite a different undertaking.
There are a lot of other non-grow complexities: route to market, sales projections, equipment delivery build/lead times, construction sheduling, marketing, supplies, vagaries of the licencing authorites (jobs-worths with no skin in the game), services supply, security, recruitment, management systems, operative training etc etc etc. This is not just setting up a grow - it is setting up a factory and a substantial business with few proven precedents.
A formidible job but not impossible. Best of luck to you all. I watch with interest and wish you all success. I have seen some good stuff in this thread and am sure it will get sorted.
