Bus to Sumbawa

Hi,
I am landing in Mataram in a few days and want to make my way by bus + ferry to Hu'u (Lakey Peak).
Can someone please let me know which bus stations the buses leave from as well as an approxiamte schedule ?
I am landing around 6PM and was wondering whether I had any chance of catching a bus straight off the plane ?

Thanks

I don't have much info for you,but, ask for a bus to Dompu. Those not very familar with Sumbawa and outside surf world probable won't be familar with Hu'u/Lakey. It would be a bit of a hell trip I think by bus.
