Unfortunately our manufacturing service is only available to orders from our ExpressPCB design software.
For manufacturing orders from Gerber files we recommend you try EasyPCBUSA.com, they utilize the same PCB manufacturer as we do, so we can vouch for the quality and on time delivery, it will be second to none. The online quote form is very easy to use. They can be reached at Support@EasyPCBUSA.com if you have questions.
