Hope you can help

I have a set of points evenly distributed to 500m intervals, and stored elevation.

I want to find from a given location any other point with the lowest elevation within a 1,000m search from the originating location.

Do this again to the following 500m away point strictly searching for points with lower elevation to avoid including the previous searching location.
