Developer to create photo image viewer/tagger

I collect road imagery at 30m intervals that has geotagged EXIF data which we use for road condition reporting. have for each road chainage data which is a data base of coordinates along the center of road, road name and distance from start of road for each coordinate. I will require the images to correlate to the chainage database and at the start of this process will rename the imagery with road name and chainage point. I need to be able to watch the imagery like it is a video and when I encounter a group of images that represents a condition I want to report on. I need to select the first image in the group and the last image in the group and then be able to tag this group of images with predefined repair treatments and add some additional text as a tag about the condition. This process will be repeated along the road until the whole road has been completed and all the conditions have been found. At the end an extraction of metadata from the images with a desired output of a spreadsheet with rows of collected data with folder name (that represents the group of images). I will also be requiring the ability for the image viewer to control a second image viewer where the user can review imagery captured at an earlier date for comparisons and when a condition is found in the first viewer will only save out the images as per the first viewer. I will require a price estimate with an upper limit for this works from the freelancer.
