Creating a video sketch

There's a video from the wedding. The duration of the video is about 5.5 hours. It is necessary to mount a video sketch about the young, i.e. Not for any particular fragment of the wedding, but so that about 3 minutes will include all the most significant and beautiful moments from the wedding. You will need to view all the videos, make a plan of what will be included in the video sketch (you can use the time code), then mount a draft version and if the young people like it, then do clean. Video sketch should be colorful, bright, with congratulatory inscriptions, animation, etc. Under the video substitute soundtrack - a song on! Russian language! Wedding themes.

I'm interested in price, timing. Examples of work are required.
