Find professional metal gate repairs in South Brisbane

I have bought all the materials from Bunnings but need someone to anchor the posts into the concrete steps and drill the holes to hang the gate properly

I would like a metal security gate acid dropped or sand blasted to remove paint and rust. 210cm x 110cm. I am located in Camp Hill so can be done on-site or taken away to be done. If the price is unrealistic then please advise what the cost would be please as I have no idea. Thanks

Gate needs to be lifted to close properly so needs some adjustment so it closes on its own and locks

I reversed into my automatic gate and slightly bent it. I need it straightened if possible.
