5 Electricians in Upper Walthamstow

I have a Nest outdoor camera that I would like installing. It will be fitted to brick at the back of the house (outside upstairs bedroom). It then needs to be plugged into a socket in the bedroom.

I need an electrician to Install 2 ceiling pendants in the bedroom. both with a wall plug. They'll serve as bedside lights. I'll provide the (fabric) cables. Install 1 ceiling pendant in the living room, needs to be repositioned above the dinner table. Install 1 ceiling pendant in the living room, needs to be repositioned above the coffee table. Change 2 (ceiling) lamp holders from bayonet to E27. Install one 3-gang dimmer.

I bought a Radialight SIRIO Electric Panel Heater/Electric Convector Heater thinking it had a plug but it has to be hardwired (see photo) so I need an electrician for this.
