Bill of Materials and Estimate for Kitchen Timer

- We get a kitchen timer manufactured in China. It's a standard product but there are some small adapations that are made to it.
- I'd like to make some enhancements to the timer but I don't have the circuit designs.
- As an initial step I'd like to send you a sample of the product so that you can produce a costed bill of materials for the current product including estimate for assembly. I want to get an experts view of what the existing product should cost to produce.
- If this is satisfactory I'd then like to work with you to look at making the changes to the product, producing a sample and working with a contract electronic manufacturer to get it produced.
