I need a business planner

I am interested in purchasing a wine bar in Oakland, CA. I will need to apply for a business loan and will need a business plan. The wine bar is already operational with a fully functional kitchen and 1600 sq ft of dining space for patrons. This business is being sold for 200k. Its yearly revenue is 600-650k. I’m hoping to acquire the space so I can become self employed and realize my dream of owning a restaurant. The wine bar has ample space to host events which will add additional revenue. Also, with a fully functional kitchen I can provide food and pastries to pair with the wine. I also plan to provide catering services as a part of my plan to grow and expand my business.
I’ve attached the listing with details on the rent and lease.
