Already made?
Then we may be too late with the PCB.

For A - please research acid traps - you have several.
For B - if you mitred the tracks a bit more you could get that copper to join up
A suggestion to reduce a long track. (done using the Win7 snipping tool - lol)

Move the top 2 grey ones and you can reroute the one with the crosses on & via a lot closer.

It looks like this is floating copper - this is bad as its an EMC susceptibility issue, connect it to GND.
(yes I know the red dots(holes) are in the wrong place - I did not bother checking the reading format).
If you want to keep the design secret then remove your attachment.
The boards you have ordered, will they be in a panel or single cut?
If you want to make these yourself you'll need a paste screen (these can be got cheaply too) and a toaster oven to melt the solder paste.
Try getting a few more quotes on the assembly, for 10 I'd think more along the lines of £100 in the UK for just assembly.
