新加坡采购需求：文具和纸张、便签和记事本

I'm in the market for customised memo pads for my business. I'm interested in square and rectangular formats, and I'd like to incorporate a unique design. If you have any standard sizes available, please share those details too. I'm considering an order of around 50 sheets per pad, with a total quantity of 50 to 200 pads based on your pricing. Could you provide me with your pricing options? Thanks!
