Random Block Wordpress Plugin ( NOT Gutenberg )

We require a small, lightweight wordpress plugin that will randomly display blocks. This is NOT gutenberg blocks but blocks pre gutenberg. The app will let you select several blocks that will be the random elements. Then the app will provide a shortcode or better ,a page builder ( wp page bakery ) element to add to a page. We want the app to randomly select one of the blocks each time the page is loaded. To clarify here is an example We have a series of blocks 1-10 We want to randomly display blocks 1, 4 and 7 on the homepage. Each time the page loads it loads a new block Must be able to speak english Must be doing this yourself ( NO outsource companies ) MUST reply to me personally. non of that pre formatted "I understand you project XYZ" garbage. Take the time to talk to me and ask me questions. Automated responses get little to none of my time. Don't ramble on about being an expert... everyone on Freelancer says that. Be original... earn my business. Must have experience creating wordpress plugins. Must be multisite friendly. Do well and I have lots of work
