@janux, things may have changed since the time you asked the question. It is still relevant to post on the Job Board, however there is a more direct channel to seek a Bahmni Coalition partner. You can specifically request to be put in contact with one here.
What happens is this. If you specifically request to be put in contact with a support partner, they will all see your request and be given the opportunity to engage with you/your organisation. This is a transparent process where all coalition members can see which one(s) of them raise their hand when a client request falls in. Usually the default response mechanism happens based on the location of the organisation seeking implementation support. I personally don’t think it is the most relevant factor, so I would advise to be as clear as possible as to the sort of skills/type of support or servicing that you are expecting (rather than just saying where your organisation is or where the implementation site is).
You may as well provide a link to a relevant Talk post if there is one already detailing what your needs are. That’s to avoid typing again or pasting things that have already been written elsewhere.
