Looking for someone in London with a machine to seal rectangular "pull-open" sardine tins for a Xmas project (Will pay!) 🌲🕯️

**Hi everyone from London!** 👋
**I’m working on a Christmas project: making candles inside rectangular sardine tins, and I want them to have that authentic "ring-pull/pull-open" lid.**
**Here is my issue: The industrial machines definitely work for this, but I don't own one, nor do I know** ***anyone*** **in London who has a seaming machine with the correct rectangular chucks/dies to seal them. Even though I’m completely willing to pay for the service, contract packing companies usually reject small batches.**
***(Note: Since these are candles, food-grade/vacuum sealing is absolutely not required. I just need a clean, mechanical closure for the lids).***
**I’m looking for solutions or leads:**
**1. Does anyone here own (or know a workshop/maker-space in London that owns) a manual or semi-automatic rectangular can seamer who would be willing to seal a batch for me? (Happy to pay for your time/machinery use).**
**2. Are there any boutique packaging services or local shops in Greater London that accept small-scale contract seaming for promotional/gift items?**
**3. Failing that, does anyone know a reliable UK supplier for "Press-In / Self-Sealing" rectangular tins where the ring-pull lid just clicks into place tightly without a machine?**
**Any leads, shop names, or contacts would be a lifesaver. Cheers!** 🍻
