Convert my CodeKit configuration to Gulp

Job ID: 31587968

Budget: $30 – $250 USD

I'm looking for someone who can either quickly convert my CodeKit configuration to Gulp or mentor me over a few days to do it myself.

The project is https://github.com/Mashweb/web-call.cc/

Tasks:
1. Remove all old files and folders from the Build Folder.
2. ESLint and minify certain JavaScript files.
3. Compile a Stylus file.
4. Process CSS files with PostCSS and its autoprefixer plugin.
5. ESLint and minify certain JavaScript files and bundle them.
6. Copy certain files to their output paths.
7. Compile Markdown files (*.md).
8. Run JPEG, WebP, and PNG optimizers on some files.
9. Cache-bust some files.

Even if you can automate most of these tasks with Gulp, that would help me a lot.
