Follow you dreams buddy! However, if the 4K start up amount is your hurdle, then you should be aware that it'll cost you a lot more before you even sell your first drop. A cidery costs a lot in overhead. As saramc pointed out, there's a lot more to it than just getting the license. You can't just have a winery in your basement, you'll have to buy or lease some commercial space which will probably have to be modified to meet regulations. Equipment gets expensive fast as well since you can't turn a profit using 5 gallon carboys. Then there's the paperwork, taxes, and regulations which will take up as much of your time as actual production and a whole lot more I'm not going to get into now.
It'll be a lot of work, but rewarding when done. Talk to you local wineries and breweries about starting up, equipment, the market etc. People in this industry are typically very open and helpful. Feel free to PM me with any questions.
Good luck!
