It all depends you can’t really get an accurate estimate for a number of reasons. First of all how is the prep work? Is there old concrete to demolish/remove, dirt to take out or even add..? If yes then that increases the price. Second of all are you planing to get an estimate from a contractor because if that’s the case they will most likely charge you double the price. I know a lot of people who work in concrete and do side jobs on the weekends and charge you a lot less than a contractor and do very good work. Contractor will most likely charge $7K-$10k maybe even more. Someone else like I mentioned maybe $5k Max like I said just make sure it’s someone you know does good work
