You will probably need around $3k to $5k for a set up that will produce that much, that fast
Then you will need to germ, veg and flower unless you get clones plus setup, electric bills, water. Once you harvest you will need another 5 days of drying and at least 3 weeks to cure. Add the cost of maintenance, time and you should be pretty close to your goal in about 5 to 6 months, assuming you have zero issues along the way.
Good luck
