Change the firm details at the footer of the letterhead

I need the details changed in the footer of the letterhead (attached) ASAP!

The new details are:

PAIL Solicitors Limited Company Number 13350694
VAT Registration Number 378343075
Solicitors Regulation Authority Number 827265

Please delete the old details which are:

Solicitors Regulation Authority Number 511025
VAT Number 946835872

I need this done in the next 10-15 minutes and I'll pay £15 because it's urgent.

The letterhead image must be very high resolution.
