I already have a motherboard for my device. Its a medical device, and the time when i get it manufactured, the manufacturer was unable to add some stuffs that was required.
Now i am in search for a new manufacturer... or may be different people specialized in different things. As i have talked to few people they are PCB designers, one is manufacturer and one will get all the components for the motherboard.
Firstly, is it good to get things done from different different people for different types of jobs, or should i look for some big company which can do all the stuff for me. Money is as usual constraint with me also.
Secondly, if i get the design work done from any designer... what actually his role in the project? Is only the implementation of idea onto boards with circuits or something else also?
I am stuck up with this work.... i have some ideas and i have a list of all my local designers and manufacturers, but i don't know how to start....
Please guide me, that i should know a bit before talking to them and also i could judge that they are genuine or not.
If any links would be given, which can help me understanding my problem, it would also be a great help.
Thanks in advance.
