Sorry for the late answer ,i just back to the office from Shanghai .
for this project ,our company need about 2 months to finish all the products . if the customer want send it by 3 batch:
1) After i get the down payment ,then i will release the production , the first batch is 30 days (delivey time) + 15 days (transport time from Nanjing to Thailand) ,so the total time is about 45 days from Nanjing to Thailand . then the senond batch is 45 days +15 days= 60 days ,the third batch is 60 days +15 days =75 days.
This is the total time .
2) so if the customer want the fist batch on Jan 15th ,2015 ,then you shall pay it at the end of Nov ,2014 .
3) there is no additonal cost .
4) the factory will not work from Feb 14th to Feb 28th because of China new year .
if you need other information please tell me .
