I run an agency and most of the requests we get would be very high level like,
'I need a review tracking system for my product, How much would it cost?'
Even on freelance portals like Freelancer and Upwork, I see this a lot. Sharing some basic information on what you want the product/tool to achieve and the features needed would go a long way.
So we built this tool to collect some basic information for building a product. Initially, it was a google form now we added some more features like the option to download it as a PDF document and the ability to visit and edit it whenever you want.
Hope this is of help.
This still has some rough edges but please feel free to use it and share your feedback.
