Need a mechanic to help me (Bend)

Hello, I’m trying to find someone who’s mechanically inclined to help me fix my car.
It’s my way of living due to being homeless.
I bought my car a while ago.
It’s a 2004 BMW 525i.
It’s got clogged catalytic converters.
I have the catless headers for it, I just need help putting them on.
I don’t have money to take it into the shop.
Can pay you with food or I can give you what money I have.
I just need it fix or we can work out a plan.
