Update existing Logo, business cards and sign

We have a logo we are happy with but we are changing the company name from MW Fulfilment to Smooth Fulfilment so we need to change the logo. Would like to keep the logo as similar as possible just replacing the MW with "S" or "Smooth".

Once logo is approved, the logo will need to be updated across our business cards and signs along with the change of address.

We have all the files in editable formats and will need them once updated in editable files, attached here is png of the logo and the sign, business cards will be sent to the person we go with.

I need fast turnaround, no limitations and creative and quality work please.
