Good luck finding a good vendor, sometimes the hair isn't the best quality. It is hit and miss. My wife was buying Indian,Malaysian,Remy, Brazil, Princess, Peruvian etc and selling it to women off of FB making $4,500 month. Until, the quality of one shipment killed her customer base, and she didn't enjoy hairdressers and her friends' friends talking bad about her. She is very sensitive to what ppl think about her.
Moral, order small quantity and test, retest, order again and pray it is same quality.
BTW when she wakes up in the morning I will try to get information on some vendors that she thinks may work. The best from what I remember is Princess kind and they want orders of $3,000-$5000. If you don't care about quality as much I can drop some names in here tomorrow.
