creatingperfume.com is offering a kit with 100 ingredients. If you are a serious starter in perfumery or lack a lot of basic ingredients, you could consider this option. The $800 price tag may be pretty impressive, but considering you are only paying $8 on average per ingredient (in 1/2oz and 1oz sizes) it will give you a kickstart in recreating my formulas and experimenting by yourself. It's a total of more than 1.5 liters of perfume ingredients, that will enable you to make between 6 and 15 liters of perfume, depending on the strength.
Only add alcohol and follow some of my free formula's on this blog and you are ready to go :)
