I've tried the 900mhz wireless transceiver. which needs a clear LOS

For usable throughput at reasonable power you definitively need the
LOS path.

To get LOS, all you need is to move your antenna high enough. Towers
up to several hundred meters high are available commercially. Less
reliable solutions are flying the antenna under a kite or a balloon.

If this is too expensive, I would suggest moving to a more densely
populated area. You will have to find an optimum for the cost_of_land
+ cost_of_telecommunication.

As others have suggested, it might be enough if you have a LOS path to
your neighbour and they have a LOS path to their neighbour and finally
one neighbour have LOS contact to the ISP.

One other solution would be to move a repeater to a hilltop visible
both from your site and from the ISP, but there is the problem of
powering it. Solar cells might be an option, unless you live North of
the Arctic circle or the sky is cloudy all the time.

A passive reflector at the hilltop might also be possible, but this
will require very narrow beams, which will require large antennas at
both ends of the link, in practice in the upper microwave bands or
even IR or visible light. However, at these frequencies clouds etc.
will disrupt the communication.
