Yeah as casper said don't cheap out, you will regret it later.
I have a second hand 6d MKii that the school bought off one of the teachers for me, think they paid £1000 for body only a few years ago. I have an old coming on 12 years canon 70-200 mk1 F2.8 lens and a relatively new Canon 50mm F1.8.
Check with WEX, you can sometimes rent different cameras for not too much and test them out.
Don't forget you will need SD cards(i keep about 5 on me at all times when shooting, ive had a few fail mid shoot) a decent bag and possibly a tripod(dont cheap out on this either).
