Yes, during CNY period the cost will increase. i had my confinement during CNY in 2008 paid about $2.8k not very experience lady (only 4-5 yrs experience).
I ever asked the price for CNY, alot quoted $3k above depends on their experience. you can try your luck with Mrs. Lee @ 96916773. She is my ex-confinement lady. If you need more CL contacts let me know.
