From memory in another post you were direct linking to a exercise type site and it probably has now every keyword showing a rating, being why your clicks have plummeted.

That being so you will need to now delete every one of those keywords and ads in that order and only then delete the campaign.

The reason being as long as the sun comes up each day you will never float that site in the link format you have currently with adwords, it will not happen, you would need to build a land site then have them go to your destination / CB site with that product.
With that i am not sure of any one at the moment here who is offering training but you may find some one, but i very much doubt you will find any person who will teach you for free.

the reason being if you look at it from the other side, in general most people may spend many thousands of dollars perfecting the craft known as adwords, mistakes or learning curves here have a large cost factor.

Next is why would some body want to carry around and drag somebody along, chipping away at their heels like a pesky small terrier at their ankles barking away for no return, they simply do not need the distraction, nor do they need the money or a promise of a little penny if it goes good as they can simply and quietly start another campaign and make more with no fuss.

In saying that there are some adwords trainers (see the wso section) who charge some big $ and that is where the good information and training will be should you wish to go the training route.

So rather than the current option you have, instead buy good quality guides from reputable adwords people, read googles guides as well, save up and buy good training in addition if you want then slowly over time put your business model together.

Hmm, It looks like I will have to figure it out myself, I will never have enough money to buy one of those WSO's.

I found 2 reasons why my clicks plummeted: I changed the keywords and didn't realise they needed to be reviewed first. The second is that I'm getting an error saying "You have no active account-level budget", I've set a budget, but I keep getting that message.

Hmm, my clicks are slowly starting to come back, no where near what they were at, but at least they are coming in. I'll see how my campaign goes, I get my pocket money at the beginning of next month, I've still got a few things to experiment and test, if those turn out unsuccessful, I will check out that guide.

Where should I look on the forum for people wanting work done?

Cheers,
Sam
