Yes, I'm interested to see how you go.
The $150 would get me how many hours? This is an ongoing thing, I'd need you to be putting in a reasonable amount of time each day of the week [mon-fri] to keep things moving smoothly.
Making orders is very easy, you just get the sales email and save the images/note the shipping address & size requested.
Email support involves checking orders status, giving quotes, taking orders for customers who email their image and so on.
Will you be able to give this project your 100% focus during the work hours?
Keen to select you to please advise.
