Thank you for the advice!
I have tried QR offices in different markets in the past, and found the responses usually wanting (sometimes got none at all, in Abu Dhabi for example, or after days in Germany).
Traffic in Jakarta is the worst I've ever experienced (you usually need an hour for 3-5km, and I am not close to the office in the Grand Indonesia Mall), and my schedule usually frees up after office hours.
Thus I was hoping there was a) either a different search engine or b) a team of dedicated specialists who for example could be reached via email to discuss the options.
