XF 1 Replace image in XFMG

[Gladius]

I'm looking for quotes on custom development for XF1; I need the option to replace existing images uploaded in XFMG. That is, I only need the option for the image to be overwritten with a new one, everything else kept the same. No versioning. The images must keep the same url (yes, I realize caching issues). Original uploaders should be allowed to replace their uploaded images. Optionally, a permission would be added for this functionality.

Please PM me your quotes and portfolios.

And yes, I know I need to upgrade to XF2, thanks.
