Return adjacent column, from opposite column NEAREST/CLOSEST value, to entered string

This question sounds simple enough, but eluded on internet searches so far!

I want a formula in K17, to return adjacent column, from opposite column NEAREST/CLOSEST value, to entered string.

Spreadsheet attached.

When value entered in K8 is met, then F2:F127 is searched for the nearest/closest single value, then the adjacent row in COLUMN G (G2:G127) is returned.

For example if K8 = 48
Then K17 = £0.13 (Also to complete the calc * K11 = £78.00)

Cheers
