One simple (but not ideal) thing you could do is to use 'Fritzing' - if you wire all the parts together in that, it'll make it relatively easy to make your own PCB (printed circuit board) that you can solder them all to - but you will still have to use all the individual modules, it'll just save you a lot of effort doing the wiring.
Otherwise you might be better off asking another company to design the board for you based on your prototype. Seeed are based in China (mainly - they're expanding) but they provide very sensibly priced board design work, and can even produce the whole thing for you in volume.
