Get together: help with bumper removal and grill change

I'm looking for 2nd pair of hands from someone who likes to play around with own car.

My Audi has quite a bit of chrome all around and I want to make it more "black optics". This includes the front grill. I already bought a new black one (didn't want to wrap the existing one) and tried to replace it already last weekend.

A tutorial video from YT showed it is possible without removing the bumper, but unfortunately looks like I cannot get to 2 important screws without actually removing the bumper (might be a difference of mounting between a pre- vs. post-facelift version, but not sure).

As this would probably be a few hours work, anyone would like to help out with the job to save some time?

I would suggest booking a slot in a self-garage (there are 2 I know: one close to Winterthur and one in Oerlikon), where we would have all the tools incl. the lift for the car. Any other suggestions welcome!

I bring snacks and beer! Or I take you later for lunch and coffee... or you choose your price
