General Embroidery hiring question

BTW this is an example of what I'm talking about. It's a leather vest.

Contract embroiderers are who your looking for (they are operations set up just to do the work for other companies and their pricing is more in tune with what you are trying to do though that all depends on quantity.

Your biggest concerns are going to be qty and quality. Small quantities of 1-3 even for contract operations are way more expensive. Contract embroidery operations generally use Embroidery machines meant for production of doing 4 to 12 Identical artworks (I always have to specify that to people cause they think "oh 4 at a time so I can do 4 different logos... no you can do 4 items with the same logo)
Some contract operations have multiple single head setups but successful and quality operations for that kind of thing that can handle leather and do it affordably... and will be there for years to come... generally cannot price as low for more than 4/6/8 pieces as operations that have multi-heads... they can just price slightly lower for 1-3 piece prices than the other operations that handle bigger orders.

Second Leather is also one of the most difficult and unforgiving materials to work on due to the fact that you cannot easily unmake a hole in leather and if you make too many holes you perforate it where it can tear like toilet paper so balancing locations of penetrations is critical and finding someone who can do that well is much harder.

3rd Full backs are one of the most expensive types of embroidery due to the sheer amount of time involved and the time involved.

If you want more details on contract operations on how to quiz contract operations or more on the pricing side of what why and how to help understand why prices are what they are and scale the way they do feel free to message me.
