How to solder a ultra small chip
It looks like a fairly straightforward process that any company that does reflow soldering can manage. That likely won't be the same company that manufactures the bare PCB. In any case, requests for such suppliers are explicitly off-topic here as &quot;shopping&quot; questions.
Generally the process would involve using a stencil to print solder paste on the pads and then passing the board + module through a reflow oven. If you design a PCB and have it made, you should request a stencil be made at the same time.
If you are in a hurry, an evaluation board would probably be more expeditious (and will likely wind up being cheaper) unless you are already pretty proficient with the PCB design process.
