Basketball Court Construction Recommendation?

I'm looking for an outdoor basketball court construction (half court-ish size).

I called a few companies that I found online but was wondering if there are any other reputable companies members here would recommend. One of them will be coming over to check the property tomorrow (Near Memorial/Spring Branch area).

Here are some relevant points:

The ground is currently grass. It would primarily be a basketball court, but perhaps we could use it for volleyball as well. (Would hard-surface futsal style soccer even be an option?)

Would it be better to go with concrete base or gravel-related base?

​

Thank you!
