Guide to start a small business

Totally new to all of these but really enjoyed colognes and was exposed to an oil fragrance store for the first time in San Diego and now me and my wife wants to start a small fun business like it as well.

Starting to do some research im seeing Scent Bazaar is a good place to order some Oils?

And please correct me if Im wrong, starting this with mixing the oil with perfumers alcohol?

25% or less oil and then 75% is pure perfumers alcohol? If i start with scent bazaar, do i need to add other stuffs? Fixatives?

Im pretty sure this is a very dumb post for some so i want to apologize in advance. Still learning and just really excited too. Hoping someone can guide us in the right direction. Thank you!
