Kinda late to the party.....
Any good vinyl sign shop can make everything you need. I know mine is not as ornate, but I don't think I even have 300 into the graphics. Most of the corporate logos can be found at I Say Ding Dong (https://www.isaydingdong.co.uk/) Great folks - and will pretty much make any changes you ask them too.
Here is my car, as well as an MG I have in the collection. I Say Ding Dong did everything less the roundels, numbers and Telefunken stuff. On the MG, I emailed them the attached pic and we spent 20 minutes going through everything.
The font for the numbers can be re-created at https://doityourselflettering.com/
