I can easily understand that the cost of shipping and purchasing can be a problem for somebody living half way around the world, relative to the supplier.
However, a side stand is a very simple little item and I think that if I were in the situation I would cut up my existing stand leg, crudely weld in a suitable extension and form a bend to suit if required. When happy with the result I would then find a workshop to make a new leg and/or bracket from my pattern. This would give you exactly the geometry that you require and would certainly be cheaper than shipping from the UK, with the unfortunate possibility of buying something that was unsuitable anyway.
My own side stand allows the bike to lean just a little more than I feel comfortable with, as you see from my avatar, and is irritatingly difficult to reach with the heel or toe to lower it when astride the bike.
Perhaps I should follow my own advice then.
