I NEED A BOOK MARKETER (HORSE RACE BETTING SYSTEM)

I have an Amazon KDP book which explains a horse race betting system based on statistical logic. I live in a country with a weak currency and can therefore not afford to advertise the book in dollars or pounds. The book sells for $10,68 in the USA (£7,89 in the UK) and my royalty is only $4,26 per book (£3,03 on the UK). I'm prepared to pay the marketer 50 cents (US) or the UK equivalent per every book sold per month up to 100 books and $1 (US) or the UK equivalent for all books sold after the first 100. Primarily, the British, American and Australian markets need to be tapped. Naturally, the books need to be bought from Amazon. The mechanics of sales determinations and payments need to be discussed and agreed upon. I also have a few low-content books that could be discussed.
