Best Website to find space for business?
Hello, new to this world - What is the best resource to find commercial space? Specifically looking for outdoor space, especially if it's on a rooftop. Los Angeles area.

Most of the sites I see it's general commercial buildings and all indoors without the option to type in keywords. 

Edit : It's for fitness classes, long term lease

No broker, but I could get one do you recommend that?", "replies": [{"id": "fyyqlx7", "text": "Absolutely find a broker. They will get paid by the landlord and will handle the whole deal for you. More than likely a broker will present you a lot more than just what they find on costar.", "replies": [], "depth": 3}], "depth": 2}], "depth": 1}, {"id": "fyyeaxs", "text": "Are you looking for temp space for a film shoot or something shorter term?  If so, lots of people use peerspace in the Los Angeles area.  If not, loopnet and AIR would be your best bet.  Sometimes you will need to work with a broker who has full access to those sites in order to find more specific spaces.", "replies": [{"id": "fyygizy", "text": "It's for fitness classes, long term lease. No broker, how would I go about finding an outstanding one is that what you recommend?", "replies": [{"id": "fz07uwa", "text": "Unfortunately I cannot reccomend myself due to the rules of this subreddit, but I would recommend looking up properties that could work for your use on loopnet for free and contact the brokers yourself to start. You can ask the brokers if they would be willing to assist you at finding a space.", "replies": [], "depth": 3}], "depth": 2}], "depth": 1}]
