Childrens Clothing - Patterns & Cut Make & Trim

Hi there, I have approx 20 designs in total for girls and boys clothing that I want to get made to approach stores with my first upcoming collection for my label. I need two different services: Pattern Making/Grading and CMT I have decided instead of making myself on a smaller scale that I want to go ahead and produce here in Melbourne so the garments are Australian made. I want to source a pattern maker who can competently create these patterns for me and grade the sizes also. Looking to source costs per pattern or whether you work by an hourly rate what that would be and approx time frame in which you could produce these designs. I have a fair idea of costs charged etc for womenswear as I have dealt with this before so I assume it will be much less due to less time to produce, sizing being much smaller and fit/toiles made should be a bare minimum. I would like to get samples made of each in which I would supply all the fabric and trims required to make the garments. Which I plan to use to market and gain orders from stores so these need to be to a very high standard. I would like to get a cost of approx how much you charge ie per garment for the CMT. There are dresses, skirts, tops, pants, jackets, shirts etc just an idea of the work involved. Nothing too complex with the designs. I can also send through images of the designs after I have an approx price and have decided to deal with you. I would like to find someone who would be happy to work with a new kids label and be able to work with ongoing and increasing orders as business progresses. I am also looking to make a good relationship with a company who is reliable and can work to timelines and to a high quality standard. If you would be interested please don't hesitate to contact me. Thank you and look forward to hearing from you.
