Here is a list

I don't personally endorse any particular company. Some of the questions to ask yourself are:
How many bottles of tea do you and to bottle?
Where will you be marketing your product?
Is it possible to get some co-distribution agreements?
Is it possible to co-market your tea?
Is it possible to distribute through restaurants, chains, etc.?
There are a several other questions on my list, but that is enough for now.
The secret to success: I have had the pleasure of knowing and working with some of the biggest names in business, celebrities, actors, entrepreneurs, business people, and companies from startup to billion dollar operations. The number one reason for their success is doing what they know and love while doing it in new, creative, and innovative ways.
Best of luck,
Take massive action and never give up.
