c# video software project needs some finishing up

PROJECT BUDGET $150 The software is a video editor, 95% of the work is now done. I need to make some minor changes to the software. Basically want to make it more user friendly. Budget for this work is $200 1. Need to make the loading of saved items a little different currenty this is previewed in the main form, but want preview/loading via a popup form so the preview and so on can be bigger. 2. This will also require 2 saved formats, one for projects, and one format for templates (in reality the saved files are zips renamed) in the templates I will have to manually add a small video that gives a preview of what the template is, so that in the load/preview part in 1. it will find the video and play it. 3. With the templates need to hide some of the options from users in the Property tabs so that they can't edit more than some basic settings. 4. Sofware uses a timeline, I want where the timeline is shown to use by default a different display, where we show just 1 item (although items will be on the timeline) want to display things differently. Basically if its a template will use a preview image and show how many seconds it is. If its a user video will show a preview image from that ... 5. Adding sound will need a couple of new options to loop till end of video, and/or to shorten to fit total video length.
