Wow. Amazon + Adwords as your first affiliate campaign. I think I'd rather take a nice warm bath in a tub full of scissors and Tabasco sauce.

I'd advise you to use what you do have to the maximum effect. I get the sense that English isn't your first language. Try focusing on markets that use your primary language, and products that are popular in your area. Your ads will be received better if they're understood completely. This can actually be an advantage over your competition. You may be the ONLY person even trying to sell in your country; you may have the entire country as a "niche" all to yourself for some products.

Pay particular attention to the content network. Advertising very selectively in forums that are geared towards or presented in your native language could be a goldmine; be careful though. Content is even less forgiving than search.

General tips for noobies to PPC.

Start with a preset, predeposited amount in your Adwords account. Don't just link it to a credit card with a high limit. It's very easy to dump hundreds or thousands of dollars that you didn't mean to spend by missing a tiny detail like turning off the content network until you're ready to use it.

Better yet, find vouchers and use Google's money to experiment with. There are a couple of resources here that can guide you in the right direction.

Start small and tight. Find 20-30 (no more than a few hundred) keywords that you think will convert and test them out on exact match with high bids. This will do two things: it will help your CTR which ages your campaign favorably (remember Google wants to see what happens during your first two weeks or so of a new campaign before they really settle on a score for you), and it prevents you from accidentally blowing your budget by bidding on a bazillion keywords and not realizing that you
- left in a bunch of shit you should have hit with a negative match (free, trial, scam)
- accidentally broad matched because you were tired or in a hurry
- wrote a really catchy ad that gets a shitload of curiosity clicks that will never convert
etc
etc

that's all I can think of off the top of my head.

Be careful and good luck with it.
