I think it depends what type you are looking for. Premium products or will products with no brand will be ok for you. I think the branded premium products are quite highly priced in Singapore. It may be worth looking to get those from the manufacturers origin country. If you say what type of brands you are looking for I may can provide you some more info as well.
Finding the right job is hard work. I know that from the past. My friend might need a sales guy for Singapore in the engineering field. If you like you can PM me some more details about yourself and I'll forward it.
I would recommend going running and doing push ups and if possible also chin ups. You don't need to start with intense training. Most important would be to do it consistently.
