Need help installing external fence panels and posts

I'm looking for a reliable handyperson to install an external fence around my small backyard. The job includes setting posts, attaching panels, and ensuring the fence is level and secure. I have roughly 20 meters of fencing to install, with 1 gate. Materials will be provided by me, but I may need advice on post holes and concrete type. Ideally, you can start soon, work cleanly, and leave the area tidy after completion. Please include an estimate of time and any relevant experience with similar fencing projects.
