>>I agreed as a favour to my friend and have not sent a single invoice yet.

first thing, send the invoice.

then see what happens.

if nothing, then personally i'd explain to the friend and see if he/she can sort it out, it's always best to be amicable and use the leverage of the brother.

after that consider your legal options but only as a last resort
