Looking for garment factories to produce my clothing brand

[lessismore]

Hi,
I'm a small shop owner in Singapore selling my own brand of men's wear clothing.
I'm looking for small factories to produce my clothing in small quantity.
I intend to do 4 seasons per year and probably 4-5 cut and sew items for each season.
Quantity I'm looking at is about 30-40 pieces for each item depending on variation.

Please recommend any contacts of factories that can accomodate small orders like mine.

Any advise or recommendations will be appreciated.

Thanks.
