Hello,
I'm from France and I live near Briscous :) Welcome!
I know a very good caterer, who offers these services at home, parties, weddings, etc.
They are very busy, but I can give you their contact and you just pay me if they are available and you buy their service.
I have worked with them before, you can say it was me who recommended them.
I wait for your contact,
Best regards,
Marisa
