Not to be a Debbie Downer but in my opinion, it will be best to review your PCB layout of this fine pitched component. Specifically see if your PCB layout will require via-in-pad services. If yes, then JLCPCB will be out of the running as your PCB shop. This will turn your design into a HDI processed PCB. The pricing for such HDI PCBs varies with the wind. For a small batch of HDI PCBs we recently designed, we had quotes from $600 to $1800 USD out of China for the same qty (30 pcs I believe). Our email box was flooded with offers out of China and some even phoned us to follow up. The variance in pricing was amazing.
We selected the lowest offer which was from Kingford PCB, Shenzhen who did not treat our via-in-pad PCB layout as anything special. This was for a 0.4mm ball pitch WLCSP device onboard. Just a FYI..
