Digistore24 Help Required in Posting Products (Digital Products)

Requirement in details:
Hi Affiliate Marketing - Digistore24 - Digital Product Posting

I have Product Page, Sales Page & Thankyou Page

I WANT GUIDANCE TO CREATE THE PRODUCT, as Im Confused with Sales Page content & Product Page Content

If this looks silly, its obvious, as I'm new to Affiliate Marketing

Btw, I have more than 100++ Digital Products
BUT Im new to Affiliate Marketing (Vendor and Affiliate, both)!

Pls guide me in the same, creating a Product on Digistore24 (Refer Attached Pic)

Pls discuss in detail, and we will finalise the Budget
I will offer 10$ USD if it takes small time, as I hope!

Thanks
