Wholesale advice

Hello Ganoksinners - looking for some wholesale advice. Recently I
went to NY to gather wholesale buyer contact info. Found a few
boutiques who would be interested, made, photographed and posted
pieces to my website (password protected)… and have run up against
the wall of my own ignorance. How do I draft an email which will not
trashed immediately? How often to re-email? What kind of exclusivity
is standard? How many pieces does one present? Do I need to take
those pieces off my retail website? Does anyone have a sample
wholesale contract or any info that I could use? Thanks so much -

Blessings,
