Tailoring alterations central Bangkok - help!

Any recommendations for a good alterations service in Bangkok in the Silom area?

For several years I've taken a variety of alterations jobs to the two ladies who ran an alterations service in a small shop located in Sala Daeng BTS station - one of the last few shops on the left as you leave Sala Daeng BTS and join the overhead walkway connecting to Silom MRT station by the Dusit Thani Hotel.

I went there today with several jobs, but the shop is empty and the people have left -- maybe the result of falling business dunig the recent troubles, although the shop always seemed to be overloaded with work. Any suggestions for alternative aterations services in the general Silom area?
