If you are very concerned about taking on a non beginners model, then you could leave it in the box for now, and buy a kit more suited to your level. This will be a good skill building exercise, give you confidence and a sense of achievement, and a finished model to sail. I did read somewhere that many new modelers take on projects that are too hard, lose hope and give up modelling, which is a shame.
You might find that Hobbyking (online, based in Hong Kong) will have some of the power systems you would want to use.
As for lathe work etc. If I was where you are, I would try to find a little backstreet workshop that will be willing to do a one-off item. This will be cheaper, and possibly easier than buying tools you may only use once.
Living in China it used to be almost impossible to find the tools I wanted (unless I wanted to buy a shipping container full). But now with Taobao, I can find almost anything, the biggest problem I have is working around the Chinese language (Google translate helps). I hear that Alibaba (Taobao, etc) is establishing in Malaysia. That would be a good source, in the meantime, you could use Taobao in Chinese and see who will ship to Malaysia.
