Looking for an electrician in the city to wire up a couple of table lamps. I have the bases and shades, but not the fittings. It's a simple job and I would do it myself, but for the life of me I can't find the fixtures anywhere - I've tried Amorn, Home Pro, Baan and Beyond and multiple small electrical shops as well as online with Lazada and Shopee. Any leads? 

You mean like this:

 

https://www.lazada.co.th/products/new-white-lamp-power-cord-w-dimmer-switch-ac-250v110v-us-plug-i274926317-s437075914.html?spm=a2o4m.searchlist.list.4.b1ae2b2cXgCQ0f&search=1

 

and this:

If you would rather not by online walk along Sridonchai between Pantip Plaza and the south east corner of the moat and you'll find at least 4 shops that will stock electrical fittings.

Thank you both. Some good leads there (arf).
