Hello 'triveleung',
<< How I increase my allowance so I can list my product to eBay?>>
Is this the ebay user ID from which you wish to do your selling? There are restrictions placed on new users -- meaning new IDs even if it is held by a long-time seller who has been selling on another ID.
If you have not bought anything on ebay, you really ought to buy a few items first before endeavouring to sell. To begin with, doing so will familiarize you with how the ebay system works.
Also, you will get a little feedback. Buyers are suspicious of sellers with zero feedback. Moreover, you can buy all sorts of selling supplies on ebay, like mailer envelopes, bubble wrap, paper, packaging tape, labels and so on.
If you have not already seen this link about restrictions on new sellers, it is here:

For every new selling ID there will be a 21-day hold on your funds as well. That means even after the buyer pays the money is held for 21 days before you can get it. However, you still have to mail the item right away. If it arrives quickly and the buyer leaves positive feedback, you will get your money at that time.
The reason for the hold is that ebay want to ensure you are a trustworthy seller. So the sooner you get the item in the mail, the sooner the buyer can praise your efforts, and the sooner you will be paid.
This explains that:

The best way to increase the number of items (and the dollar amount) is through consistently positive sales, -- prepare and post accurate listings (including correct shipping fees), promptly mailing the items, responding politely to any inquiries, -- basically great items and excellent customer service.
Best of luck
