I am quite sure your project can be made with a smaller chip than a PSoC5, PSoC3 would be enough and depending on the complexity of the software even a PSoC1 would do the job, but they are more difficult to debug (ICE).
I'm afraid that this forum is not able to give you pricings and quotes neither for chips nor for the design of a board or the manufacturing, soldering etc. until up to the software.
These forum here is for the help of developers to circumvent problems they have in designing and / or programming of PSoCs.
There is a list of consultinng companies to find here at Cypress's website (at top of this page: Support->Design Partner Program). Depending on where you are located you may select some partner(s) to co-operate with.
Thanks for your response, Bob.
