Hey @Sperable – can you provide me a little more detail?
What is the project, what are the goals and deliverables? What is the industry and other company details that can provide context?
If it's your company that is being developed rather than you delivering the work for the client, I will create the proposal with you as the client. – With this in mind, what sort of company would you engage to develop your company? Would you be considering a Management Consultants, Marketing Consultants, etc?
