Affiliate Marketing Secrets

Hi,thanks for reading.
Im in a bit of a dilema, i have been given a business by a dear friend of my dad.
He had invented a cleaning product that is in my opinion the best the market has ever had! not mentioning names but they are nothing good compared to this product…it had even been used in buckingham palace and given the queens stamp of approval ! he has teached me the secret ingredients and method of producing this product but im at a loss where to go with it? When he was in business he did everything solely in his garage at his home & made a comfortable living from it. He ceased in business due to ill health and a marraige breakdown but was on the brink of having large interest by an american cleaning company..not mentioning no names…I am still young at 29 but i am a hard worker and committed to everything i do. I just dont know how to start having little money to start it up again can anyone give me good advise on how to go about things ?
any advise is valuable….thanks
