VBA macro to fill down formulas for several columns via a loop

I need a freelancer to write a very small macro that will fill down my formulas column by column and copy and paste the values in each column in a table. The macro must be written as a loop as I will be applying the macro to a very large table with volatile formulas. The macro must not do all the columns at once as this will make the macro run far too slow. The size of the table may vary so the macro must be able to adjust itself according to the size of the table. The starting point of the macro will always be in the same cell, which I have specified in the recorded macro.

Step1) Start at the specified cell
Step 2) Fill down formula in column
Step 3) Copy and paste values in the same column
Step 4) Repeat this process until the next cell is blank.

I have recorded the macro for the freelancer to see how the macro should perform.
