I think one of the problems in europe is that we generally work to a standard size called the "eurocard" 100mm x 160 mm or double 233mm x 160mm at 228mm ish you are going to be very very tight. Most boardhouses require a minimum border.

you will get best prices for a standard eurocard can you adapt your designs to this size?

could you get all your designs to fit onto a single double size?

FR4 is just like real estate in Mayfair, make a design as small as your ability to hand populate.

I still think you should give a bash again at making the boards yourself, just think you will not need a separate picture frame if you just tape your pcb to the side of a fish tank

Dave is absolutely right you need to press the image as close as possible and evenly to the photoresist, it is fairly critical. you could even press the whole caboodle against a south facing window. The advantage of the sun is that UV quanta is, to all intents and purposes, parallel and in addition you will not have the problem of inquisitive little stationary fish.

if a little fish has the intlelligence to be inquisitive
