Builder wanted to create window opening

[Richard_Brookes]

I am looking for a builder or window fitter qualified to create a new opening approximately 500 x 500mm and install a window in the location shown in the photos. Possibly also supply the window if you can supply something suitable and you want to supply, otherwise install only is fine. The walls are thick and solid so proper mechanical equipment will be needed. Postcode: SE15 3JN. Please get in touch if you are interested in doing the work sometime before the end of autumn (I am NOT looking for recommendations, just direct contact from people who can do the job within that timescale). There might be further work removing a load-bearing kitchen wall or two. Thanks.
