Watermark removal 3,000 photos + Data entry to WP galleries

Summary: Watermark removal (3,000+ photos) + Data entry (replacing photos in simple Wordpress website)

- I have a wordpress website with approx. 150 objects / 150 pages, each one with photo gallery (with approx 10-20 photos): https://snipboard.io/kQNmWJ.jpg

- All photos in galleries have watermark in the center of the photo, which needs to be removed
photos are different sizes, and not HD quality

So, I need you to:
1 - Download the photos from all object pages on the website, to their respective 150 folders (each named by the object - Object 1, Object 2 etc)
// Note: photos are in the form of lightbox gallery, screenshot: https://snipboard.io/kQNmWJ.jpg
- they can be downloaded in bulk from each page, with tools like DownThemAll browser extension, or similar

2 - Remove the watermarks from the center of the photo on all the photos

3 - Login to wordpress and on each object page,
- which looks like this: https://snipboard.io/NhXRPD.jpg -
- replace the existing (watermarked) photos, with the same photos without the watermarks (that have been removed in step 2.)

Please let me know your price for this.
(Ignore the specified project budget that I put just by default)
