for a long time, I have been doing my PCB design and manufacturing through https://www.pcbway.com/. I have been sending all my manufacturing files to them and at the end of the day, I receive my complete PCB design. Currently, am also thinking of trying other sites in my design, and a friend of mine suggested for me ALC and Sparkfun. I don't know if am on the right channel and that is why am posting this question. Also, I might not be having great knowledge on how to do the design using your sites. Any help offered shall be appreciated.
