Your concern about Sterlization is right on target for a beginner. ALL supplies MUST be clean before you start any batch. Try to never lose that thought.
When I got into Winemaking, all I ever did was pour boiling hot water in the jugs that I used for the hobby. I used Hot, Soapy water and a Scoobie to scour out the inside of the jugs. And rinsed them thoroughly.
Now, even though I still use hot,soapy water, I mostly use Denture Tablets to Sterilize the inside of the jugs after they are cleaned. Believe it or not, denture tablets have a form of bleach, which is a germicide. 8 to 10 Tablets to a gallon does the trick, let set a few days then rinse thoroughly.
When I started, I had my share of flops. Now I rarely have a batch go bad.
Even though I do not usually recommend Brand Names here on GBO, I will tell you that Red Star Yeasts offer a sizable choice of Wine Yeasts. Wine Hobby Shops sometimes have a website for internet customers to order supplies on-line.
As for the help you seek, this forum may help you more than some other website, because the help here can be ongoing and as often as you need it. However, if you type: Home WineMaking in "Google" or any other Search Engine, I am positive you will get well over 1,000,000 responses.
I do not offer links here because other websites do not have advertising agreements with the ownership here.
If you need help, just ask. If I, or anyone else can walk you through the process, I'm sure you will be successful.
