Process of getting a gig as a club DJ

Hi all, I’ve taken up an interest in DJing, and have a few questions before buying a controller. I have an end state (1-1.5 yrs from now) of wanting to play at a local club/bar, but nothing more than that - just want to give people some good music; I’m not in it for the money.

I have a few questions:

• what controller should I get that would work for the club? I hear a lot of talk about the FLX10.
• should I even be starting on a controller like this as a beginner? I’m thinking about starting at the FLX4 and upgrading over time (money is a concern and will have to save up before purchasing a high end controller)
• I’ve heard that some clubs have a DJ controller for you to use? Is that the standard or does it change by club? (I ask this last question as I believe it will influence my decision on what controller to buy. As if clubs provide the controller, then I am thinking of just buying the FLX4. If not, I’ll just bite the bullet and buy something high end.)

I have a lot of questions to the whole process of how to book a gig but I will just stick with this as I know I am being very ambitious lol. TIA!
