Plumber for a small washing machine job?

I had a new washing machine delivered today but they were unable to connect it as the person who took away my old one took one of the connectors with the old machine and apparently it was not a standard one.

I went to a local plumbing shop, got 2 and none fitted (photo of the pipe it needs connecting to attached - the pipe is 1.5 inch ).

Other pipe is connected I just need someone to connect this one to where it should be.

I am on Florence Rd so if anyone local could do this for me (ideally today)- pls send me a private message with estimated price.

Attached photos of what needs to be connected to what - only this part is needed to be done but do not have the connector.

many thanks
