You could try posting a flyer at a local fabric shop, or joining an Etsy team in your area and post on there.
You should also look into a non-compete contract (you can probably google it for a template) so that the person you hire can't learn about your business and designs, then quit and open there own shop.
You might also want to check your local library. I've been surprised at how many helpful small business books I've found at mine, and they might have some useful tips.
Here are a few other threads that have info too:
Do you have employees?
https://www.etsy.com/teams/7722/discussions/discuss/12239064/"I had to acquire Workman's Comp insurance, a withholding permit, etc. It was a pain at first but not impossible for an individual to do."
Hiring Employees
https://www.etsy.com/teams/7722/discussions/discuss/6304203/"If you are a small business owner, whether you hire people as independent contractors or as employees will impact how much taxes you pay and the amount of taxes you withhold from their paychecks. Additionally, it will affect how much additional cost your business must bear, what documents and information they must provide to you, and what tax documents you must give to them." A lot of information and discussion in this thread. Some suggestions that you could hire someone as an apprentice or an intern versus hiring an employee.
