Need Access 2016 specialist to modify invoice number sequence

Hi,

I am looking to hire a specialist to modify couple templates in Access 2016.
I need to modify the invoice number (automatically generated) to a new sequence.
Please note i don't know access so you will have to know where to find the data
Also will need to replace the logo (logo provided) and we will have to check everything is working
You can connect via Anydesk to remotely access the PC.
It is a very small project for a specialist but i need it to be done now
