Hi, does Myamar maid need to apply for visa when entering Malaysia? If yes can please advise where and how to apply and the cheapest option . Thanks

Yes you will need to apply a visa for your helper before entering Malaysia. I'd suggest you head down to the Malaysian High Commission in Singapore. It's safe, reliable and there will be no hidden costs. This link has all the information you will need: http://www.kln.gov.my/web/sgp_singapore/requirement_foreigner
