Looking for Value in Another Column, Evaluating and Then Looking in Another Column

[olives]

I have a value say in Cell A1.

I want to compare the value in Cell A1 with all the values in the cells in Column B (which may have thousands).

I am interested in all the values in Column B which are lower than the value in cell A1.

If a cell value in Column B is lower than the value in A1, then I want to go to the adjacent column, Column C, and see the value of that cell, the one adjacent to the one in Column B.

Now I want to compare the values in Column C and pick the 10 or 15 highest and be put in cells A2, A3, A4, etc..

Can this be done?
