Hi Sphere,

Yesterday I posted a link of a company in the UK.

The same company has another web site:
http://www.customdesigntechnologies.com

They have a service called "customAssembly".

Try to contact these people and see If they are willing
to take some risks together with you. (Joint venture).

I am sure that they have already an eclosure with keypad
that will fit your needs, so the initial costs will be low
for them. Later on, if the product sells well, a new
enclosure with new keypad is always possible.

Good luck with your project!

Best regards,

Luciano
