I would not go with a "clone in a box" solution, but I definitely would use ready-to-use services that are out there to build what you need while allowing some level of customization.

For example, you can use tools like Wordpress (CMS), or Shopify (e-commerce), or other similar tools to build your marketplace, depending on your needs. This will allow you to get your idea up-and-running quickly with little upfront investment.

After you've proven that your business idea works, then - and only then - you can go back and invest in creating a more custom solution.
