i'm also uk, i haven't released the files yet for you to order the pcbs but as i said when i ordered my pcbs from jlcpcb it cost me £4.91 for 10 pcbs (not including shipping) so there pretty cheap to have manufactured.
i specifically made them as small as i could, you will need to solder a STM32 dev board (STM32 Blue Pill) onto the back of my pcb (facing up) and the few components you see on top and that's it.
then you just flash the firmware onto the STM32.
