How to connect 2 sites located ~115m from each other? No cable connection available

Hello, I've been tasked today to come up with a solution how to connect our second small office to the internet ASAP, because as it turns out, there's no infrastructure there and not a single local ISP can lay it out in a reasonable time. Therefore, my direct boss told me I'm to "come up with something, and fast" in order to enable internet connection in the second site.

First of all, a bit of data/facts:

- my experience is rather scarce in the matter, I've done some small networking projects on site/lab, but never connected 2 remote sites wirelessly ( I'm the only "IT person" working there )

- main "office" is a regular small house converted to an office space (at max 30 people on site)

- second "office" is also a regular living space converted to and office space, also for ~30 employees

- What's important, the second site doesn't have to be in the same internal network as the main site, the only requirement is for it to have internet connection

- both places are located approx ~115 meters (~370 ft) from one another in a straight line (in the city suburbs, so there's no "big" architecture such as skyscrappers, multi level blocks of flats, etc, just a whole lot of similarly sized houses.

- our main office connection is a 150 M fiber, but our infrastructure leaves much to be desired, A.K.A. it's a single old NETGEAR ProSafe Gigabit Quad WAN SSL VPN Firewall SRX5308 and a couple of switches/AP's/physical servers BUT that piece of garbage hardware is barely keeping up with what's already installed and doesn't even reach ~100M connection with a handfull of FW rules enabled and two switches connected

- because of the above, I'm very reluctant to the possibility of broadcasting the signal via something like Wi-Fi antennas, mainly because I'm afraid sharing the current, barely working solution with another approximately same size environment wouldn't be any good and only make it worse not only for the main site, but also the second one

- even if I was to forced to connect sites via Wi-Fi, I've basically no idea how to check/pick what kind of hardware would do the job (my initial thought is to plug a transmitter/antenna from our router [to a separate port with it's own DHCP server, etc], locate it at the top of the building somehow, point it in the direction of the second site, then install a second one on top of the other building and pray it works)

- my other idea, which is IMO much easier to implement is just taking the LTE router to serve as an quick alternative of an ISP until a proper wiring is available, but I would need to make sure the uplink is stable enough for ~30 people to comfortably work with

My question to You, wise folks of /r/networking is, which of the two solutions would you recommend? Or maybe there's a simpler solution I failed to come up with? Any bit of help regarding the matter is much appreciated.
