Hi Guys, I'm both new to this site and Bonsai. I have been interested in the art form for some time, but never seriously until now

Thanks to Ray N. for putting me onto this site.
Over the last 6 - 12 months have put together a small starter collection, nothing to crazy, well with the exception of this monster

I pick this up from Newcastle a few weeks ago, just sitting in a big concrete pot but I saw heaps of potential. The previous owner thought it was well over 40 years old. It needed an immediate repot but no dramatic root work was done. I have removed alot of branches and trimmed it back significantly to this point. As you can see from the pictures it has a fantastic base and three great trunks, the only shortfall that I can see, at this point, is the top of the trunks have been cut off flat! The trunk on the left has a nice, aged split running right to the top. Given I am very new to Bonsai any advice, suggestions and guidance would be greatly appreciated as I am at a little bit of a loss as to what too do next. I know from reading a lot of posts on the site that Privets are no eveyone's cup to tea, but as I said 'I' see a lot of potential here.
I though I would also add a picture of my small collection/display, my favorite is the 16 yr old Japanese Plum. I also have plenty of pot stock including Figus and Bansia ready for potting, shaping etc in a couple of months.
