Have no means to create an account. Come to x place, pay us to measure you, we create an account and give you login credentials.

You can change the measurements once you have an account. 

"If you aren't confident you know how to properly take measurements, we recommend getting them done by a seamstress or similar professional. Garment fit depends on us having correct measurements."

I talked to someone once who had a small forum and no means to create an account. You had to email him and he created an account for you.

It meant there was zero bot activity or spam or various sorts. 

Do account creation kiosks periodically in different places. Or establish a list of seamstresses in different places who can measure you and set up your account.

This also would help me scale the business and provide some protection from a "virtual reality check" scenario where a zillion people sign up and place orders while it's still little ole me and one knitting machine.

Initially, there will be one place you can go in person to get measured and get an account established. This will help me both gauge interest and control growth.

If people are flying in from far flung places to create an account and my account creation service is booked solid, time to buy a second machine and start arranging more sign up points in different places.

To keep it simple so I'm not dealing with a ton of employees and accounting etc., people get vetted and get the power to create an account, they operate independently and charge fees directly to customers. 

I want the fee to not be excessive. I need to find out how much time it takes to measure someone and create an account.

If it takes thirty minutes and they charge, say, $25, they will be making good money, the sign up cost will not be a big barrier to entry and I have some quality control over measurements which is a critical detail for the success of the model.

IF it takes 30 minutes to measure someone and create an account and you charge $25 for this, it's up to $2000/week income if you work 40 hours and sign up up to 80 people.

We will need to cap sign ups at 80 per week to not be accused of working people overtime etc. They will be independent contractors and handle their own fees and taxes, etc.

At 4.3 weeks per month on average, that's over $8000 in income for work that shouldn't be all that hard.

Capping signups per contractor will also help us control scaling of the company and hopefully encourage them to keep their hand in as a seamstress.

New tech typically follows an S curve of adoption. That initial J curve levels out when the market is saturated.

You will still see new signups, but crazy high numbers of signups won't last forever. It can be a nice bump in income for a while followed by a steady supplement to their regular income.

They will need to know how to measure and we will test them for that. We won't train them on that. We will train them on setting up an account.

They can charge for doing updated measurements on existing accounts if a client has gained weight, lost weight or had a baby and wants to make sure their measurements are done right. 

If they are really fast and can do this correctly in 15 minutes, cool. You get a higher hourly wage and you can spend twenty hours a week sewing or just enjoy your life working part time.

I need a mechanism I can defend in court before the labor board that isn't gamable. So you can do x number per week (exact figures to be finalized when I have something real) and that's it.

I will think on how to help them easily set up appointments to create new accounts for us and how to entice NWW customers to also buy custom-made clothes from the seamstress who just took their measurements. Maybe an information packet they can use.

But they won't be employees of NWW and the clothes they make won't be in any way directly associated with the brand.
