Hi,
As Freelancer, I can't directly contact you, unless you initiate conversation with me over chat. So, I guess you have to start it. Then, about your project, It's not clear what you want to build, can you give me a brief explanation about it and more clearly? Do you want to build your own arduino board, or something else? please tell it to me.
I will waiting for your response over chat. You can see at my review to know how I work in past project.
Best Regards,
Rijal
