Need help with FB ads

I am willing to learn but not going to buy thousand dollars programs I could have just spent on ads and figure-it-out approach.

I would pay someone to manage my facebook ads starting slow then if get success continue paying more and more adspend.

Always reluctant to spend for ads worried about losing all my money and a waste of time and money.

I have websites and products that sell now and I did not advertising methods only other marketing methods that cost me time but not money. But I could boost them with ads and get some momentum going. Things have slowed down lately and I want to get some action going so willing to do some advertising.

But I don't want to waste my money which I need so I need some help with FB ads.

Can you recommend a great course (under $100) or a great person who is reasonably affordable yet amazing who will run $100 to $300 per month ads at first so I can see if it works?

Also I need to know what type of products I can advertise on facebook, is it just B2C or does B2B work on FB ads? What price range is successful, can you do $100 to $1000 products or is it better for $1 to $10 items?

Also could use help with an easy approach to a click funnel to implement for it. I am an experienced web developer so I can build the pages themselves quite easily, it is the sales funnel itself I could use some guidance on.

Thanks so much my warrior friends.
