Freelance help with older Sketchup and Swivel plugin



I am looking for someone we can work with to make the background and put this project together.
We have been trying to develop a web system where we take a dxf from an engineering system and turn it into a finished sketchup seen that is interactive as jpegs.
We do this by using the old “AllowDXFImport” msi and then use “SwivelButtonPlugin” We plan to use the swivel plug in as it is then modify it to walk through a building.

Do you have the experience with the older Sketchup?
Thanks, Larry
