Social media photography for London

Hello,
I need original images of London creating for social media.
I would like someone to take a variety of photos of interesting scenes/places/buildings in London, both outside and indoors.
Images will be used on mainly on instagram but also other social media platforms.

I am looking for images similar to those used on:

Ideal candidate will be a blogger already, who takes pics like this for their own instagram - this is not a requirement though.
Full release/license should be given for use of the images.
Ideally looking for a long term arrangement, providing 2 or 3 unique images per week. Please provide pricing and turnaround times for content for 10, 50 and 100 posts
