Customer needs bespoke envelopes - can you help them?

I’ve had an enquiry from a potential customer who requires 90 non standard envelopes size 19cm by 15cm required in couple of weeks time for a wedding.

However I would not be able to source the correct materials, make a template and them make them for her in time. This is because I’m just out of hospital having had a operation. Is there anyone here who might be able to help her please let me know and I will email the lady with a link to your shop.

Thank you
