Plastic injection mold Manufacturing in india. What should I expect in terms of samples? "Yes, no, shut your mouth when you're talking to me!"

Hi!

I recently raised funds via kickstarter for a product I designed and am planning on manufacturing in India. I have a relationship with someone who originally helped me with some CAD design and can also manufacture my product. I have very little experience with this sort of thing and was hoping to get some insight on what to expect. Specifically I was curious about the following...

- Is there a standard number regarding order minimums?

- Should I expect to receive samples or due to the cost of injection molds is that not something usually requested?

- If samples aren't usually offered what can I do to try and mitigate errors or flaws with the final product?

- Can I expect a "re-do" if they arrive with problems? (I was going to ask if they could provide a referral for someone who has had a similar experience aka manufacturing a product and shipping it to the US. Would this be an acceptable ask?)

That's it for now. Thanks in advance for any input. I very much appreciate it as I'm basically flying into uncharted territory all alone and blindfolded.
