Zero-Cost Plans: *Modify the system to accommodate providers with zero-cost plans, exempting them from requiring payment methods.// Current system ask for payment method on free plans New category Feature/Function: *Introduce a type of category that instead of letting users select from the list of services and providers, it only lets user select the subcategory for the service they need. The system would then alert providers that have created services in the selected subcategory and allow them to bid on the service request. A detailed outlining of each feature and its requirements will be provided upon project commencement. Regular communication and updates are expected. The selected developer will have the opportunity to contribute creatively to enhance the user experience.
