Christmas Concert

I have made a 20 mins christmas video ( homemade) which I need now to convert to make it look chrismassy. I have chopped the video into sections already. Need someone with creative ideas to make this video look professional. I want to add a title page and a credit page (text to be confirmed). My idea: I would like each section to have some transistions/ amination. Each section spells out the word Christmas so maybe have some images of them as each chapter starts possibly or even have them dropping down as the kids are singing. Maybe even have some chapters in a different colour like sepia/ black and white. I leave that up to the expert. I want it looking like christmas but not like santa's Grotto if you know what I mean:-) Need video done ASAP. I will send over video once I have selected a freelancer. Thanks Jo
