Hello,
i'd like to apply for your project. It would be a very simple task for me so i don't have much to say about it. I have designed various different cards with edge connectors in Altium before and it should take about 1 - 1.5 hours for me to finish it, so it would be about $20 - $30 worth of my time. I'm also aware of physical requirements for both shape and material of edge connectors and i can specify it in one mechanical layer for your manufacturers reference. I would need board dimensions and M.2 connector type from you to finish this task.
I hope you will consider my offer and best regards,
Emir Cesovic
