I bought my kit from a pro photographer that was looking to upgrade, and with such a budget you can get a real nice used kit.
Plus a "rugged" camera body gives you street cred.
The Sony sensor on their mirrorless is outstanding - one of the best IMO - but their lack of, and expensive to buy, lenses, turns me off. Canon by far has the largest user base, thus lots of used bodys & lenses on the market.
Trust me, having 2 or 3 lenses on top of the "stock" 50mm is a lot of fun. My fav is the Tokina 100mm wide angle, I can take a pic of a wedding group 15 people wide without having to walk away over 100 feet, and yet also take a pic of a bee on a flower, or the wedding rings, with the exact same lens.
Look at Kijiji also. Look through some 50+ ads on cameras, try to see a pattern. It's like shopping for a used car, the popular ones are usually because they are good.
Like a Mazda 3 is superior to a Ford Escort.
You should see more Canon than Nikon, and most likely zero Sony.
