Replace Existing Chandelier with New Light Fitting

Hello, I’m looking for someone to replace an existing ceiling chandelier with a new light fitting. The existing light is currently installed and working. The new light fitting has already been purchased and comes with installation instructions. It is a like-for-like replacement, no new wiring or new electrical point is required. I'm unsure of how much this type of job would typically cost, so please feel free to give offers that align with normal pricing for this type of light fixture replacement. Thanks!
