Customization - Who do you use?

Are there companies or freelancers that Acumatica users call on to create customizations, do you depend on your partner, do you have someone in-house? I’m curious if partners are all at the same level and what the expectation is for customizations. I have a request that I would consider very simple for someone knowledgeable. I have sent the request to our partner, waiting for response, but depending on their workload/knowledge/skills, it may not be something they are interested in helping me with or it may be a long way out on their timeline.

All I want is to automatically print labels for PO receipts. I thought this would be easy as other software packages we have used have had this. We do not have the WMS and the existing manual Inventory Item Labels are cumbersome to process and would waste a ton of labels since it prints a whole page.
