I have signed as an amazon affiliate who has given me several drop shippers to get me making some money

You get higher selling limits by selling. By getting positive feedback. By getting excellent Detailed Seller Ratings.
You will need at least 25 sales before you can ask.
Then you can request an upgrade once every 30 days. Not more often.
