Ground cloves?
Any wet market. Buy a quantity of dried cloves, put them in a pepper mill or a Mortar & Pestle or a Blender with a chopper attachment and voila! ground Cloves. One must remember that living in Asia is a challenge. Though that isn't much of a challenge I must admit. Go to Tekka Market in Little India or for that matter go to Mustafa's on Serangoon Road both places will have it. Mustafa's will have most anything you could want related to spices or anything else for that matter and is open 24 hrs.
If one wants all the convenience of home, one must stay at home?
As far as creating a site you must remember that once the information gets too small, then it becomes a hassle to find anything. Same with putting paragraphs of explanations. I've used the concept that Expats are rather resourceful and only need a link, they can call or email or fax or send smokesignals to get the fine details.
Here's another one besides my feeble attempt:

There are several other sites as well.
