It's hard to find sellers in the UK, but these guys come up in a Google search and are £16.60 (vs £12 for the MDBT42, fully programmed - far less in quantity).
How much does the NINA BL112 cost you then? I find it hard to believe that the MDBT42 isn't substantially cheaper as UBlox are usually quite expensive.
You can definitely tell your clients about Espruino on the BL112, and yes - I can offer paid support for them. However I honestly think it'd be in everyone's best interests to stick with MDBT42 if at all possible.
