My first advice is to start with just enough equipment to brew a few AG batches, like a large kettle, mash tun, and burner (keggles are cheap and work great BTW). Also get some good fermentation temperature control ASAP, as it's undeniably one of the most important factors in making great beer. There are countless ways to set up a nice brewery for $2k, but until you've done some research and some AG brewing it's tough to know which set-up will work best for you. Read the build threads in the DIY forum for ideas, and slowly plan out how to spend the rest of the money. Pay particular attention to why people are making the choices they make in their builds. I think there's less risk of buyers remorse this way, and a higher likelyhood that you'll truly enjoy using your system.
My second piece of advise is that if you're even a little bit handy, look into building a system yourself rather than buying something that's turnkey ready. The process of putting it together yourself forces you to learn a lot, and you'll be better prepared to operate it and troubleshoot any problems down the road. You'll also be able to configure things exactly the way you want them, and include only the features that are important to you. IMO the building, tinkering, improving, and modifying of a brew system is half the fun of being a homebrewer, but I also realize that some people would prefer to get straight to making beer.
Whatever you decide, good luck!
