Do you think it useful?

Hi, I am a web developer currently build a website for cocktail lovers. I encountered a problem the first time learn to mix some drinks: "So, what else can I do with the vodka?" I bought a vodka to mix one drink, if I wanna try some other cocktail recipes, I've got to buy something more. I don't feel like optimizing my wine collection this way. So, I developed an alternative shopping guide for this condition: "These are the 10 items you should have if you wanna mix some drinks efficiently" , in simple terms, I found a way to know what a man should buy as a cocktail beginner. All he has to do is to go to the mall, buy these 10 item, and he can now mix a various kinds of cocktail with these 10. Do you think it's useful service to be further developed? Here're the sample results I calculated: ========================================= 10 esstientails:Kahlúa,Baileys Irish Cream,Grand Marnier,Lime Juice,Vodka,Cranberry Juice,Triple Sec Liqueur,Dry Vermouth,Olive,White creme de cacao, 9 cocktails from the 10:B-52,Cement Mixer,Cosmopolitan,Mudslide,Screaming Orgasm,Vodka Martini,Kamakazie,57 Chevy with a White License Plate,Chocolate Martini, ========================================== the calculation can be set to 10, 20, 30, 40, 50.... esstientials... Do you think it useful? Please tell me whether I should continue this development, thanks alot!
