Someone to attend apartments viewing appointments on my behalf

Hello dear Düsseldorfer,

I am living in Dresden and planning to move to Düsseldorf by March, I am currently looking for an apartment, and having the problem that many landlords schedule the viewing appointments during weekdays, which makes it impossible for me to attend,

I need someone or an agent to go on my behalf to attend the viewing appointment to mark my presence and also take a video of the property for a fee.

Do you know any companies/self-ezaamployed people that provide this service?

Or a company that can find an apartment for me in general?

Thank you !!
