Salary Average Wholesale Shipping/E-Commerce Lead/Manager

Cross post from r/personalfinance for help.

Due to unforeseen circumstances I’m probably getting promoted shifts into an new position at work. I’m going to approach my boss and request a pay raise.

Currently at $35,000 for an entry level whole sales rep position, being put into a shipping and e-commerce lead/manager position.

I’m struggling to find a good idea of what the market standard is at for this? I’m young and was already foolish in my interview to tell them I didn’t know what my expected salary was when I got hired on for this entry level position and when I go in tomorrow I want to be able to speak with confidence. Any help?
