New independent consultant hack for sites like Catalant: 

1) Create word doc with your team's resumes and all of your project descriptions
2) Include a section for "New project context" or similar, where you put the reqts/description of what you're pitching
3) put the doc in Claude or Grok, ask it to write a proposal / pitch for your team. 

Save and re-use with each new project context. Much, must faster than doing it yourself or using a template.
