Hello, I'm pcb designer and also I can assembly some board by reflow process.
I can assembly your board if you are interesting, please send me your BOM on attach file to see witch components you're using.
I'm in France, we can send me your board by post (with components, or I can order them for you) and after assembly i will proceed by the same way, by post, to send you your board.
Thank you
Hope work with you
Regards
Ludovic
