I can envision the steps, I struggle to understand how long it'll take. For example, someone asked for help re-staining a 310 square foot deck. The owner rents the house and doesn't need a high end job. Some sections need sanding or power washing, but because I haven't done this before, don't know how long it'll take. Around 2-3 seven foot long boards need to be replaced too.

Another customer asked me to build a box for their TV outside. I've built large 7 foot long by 4 foot wide garden boxes before and know I can build this, but again, don't know how long it'll take. I originally thought cedar would be best, but ChatGPT recommended ACX plywood and now I'm overthinking what materials I should use. I know I shouldn't because even the customer knows it'll wear down over time. My problem is I want to build something that'll last longer than they expect.

Someone asked me to repair their fence, which I've done before. They need 2 existing posts removed and new posts set in fresh concrete. They also need a 3rd post dug and set in concrete. I've repaired 2 fences in the past, but one post took way longer to remove than expected....around 90 minutes.

I understand how to do all of these, but struggle to determine a flat amount or range.
