Buying a clone script is not the right choice to create a website or marketplace for your dream business. As you mentioned, two approaches that can be chosen for building your freelance marketplace like Fiverr. I would suggest you choose a full-fledged freelance marketplace software.  Considering a ready-made solution can be a more advantageous approach compared to building a website from scratch. 
Here’s why:

Benefits of Using Ready-Made Software:

Cost-Effectiveness:- Developing a marketplace from scratch requires significant investment in terms of time, money, and resources. Ready-made solutions, like the Fiverr clone, provide a more budget-friendly option as they come with pre-built functionalities.

Time Efficiency: Building a platform from scratch can take months or even years. Ready-made software can significantly reduce the development time, allowing you to launch your marketplace much faster.

Proven Functionality: Ready-made solutions are often tested and refined over time. They come with essential features like user profiles, job postings, payment gateways, and reviews, which are critical for a freelance marketplace.
Technical Support and Updates: Providers of ready-made software often offer technical support and regular updates, ensuring your platform remains secure and up-to-date with the latest features.

Scalability and Flexibility: Many ready-made solutions are designed to be scalable, allowing you to start small and expand as your user base grows. They also offer customization options to tailor the platform to your specific needs. YoGigs is one of them that caters the demand of freelance businesses.

Clone vs. Full-Fledged Marketplace Software

While a Fiverr clone can offer a quick start, there are full-fledged freelance marketplace software solutions that may provide a more comprehensive and flexible approach.

Here’s a comparison:
Clone Software:
Simplicity: Clones are designed to replicate a specific platform, making them straightforward to implement.
Basic Features: They typically include only the core functionalities found in the original platform, which might limit customization.
Short-Term Solution: Ideal for those looking to launch quickly with basic features but may require significant modifications as the business grows.

Full-Fledged Marketplace Software:
Robust Features: These solutions are built to support a wide range of functionalities, including advanced search filters, detailed analytics, and diverse payment options.
Customization: They offer greater flexibility for customization, enabling you to create a unique marketplace that stands out from competitors.
Long-Term Viability: Designed to support long-term growth, these platforms can adapt to evolving business needs without extensive rework.
