I used a Canon T3i for a few years, and it did a fine job for me, so the more current version may be a good choice (T6i or T6r). A good kit lens, tripod, batteries, CPL and maybe a longer lens also should fit the budget. You may want to upgrade before you NEED to upgrade. Nikon also makes a similar camera in the same price range- I don't want to start a Canon vs Nikon debate; both would be very good. While other brands offer some great equipment (Pentax, Olympus, Sony, etc), if you really become an avid photography enthusiast the Big 2 will always have something that will do what you want, and will reduce the chance of having to re-invest in a new line.
But the budget you set will allow you to get started with very capable gear from many manufacturers.
