This is for my consulting business. I am a sole entrepreneur with 30 years experience as a lawyer, now providing business advice on how to structure partnerships, especially ones where the international community addresses development topics (like refugees, famine, agricultural research, climate change, etc.). These structured partnerships involve governing bodies, trust funds, secretariats, donors, and developing country beneficiaries. My practice emphasizes stability (good common ground and agreement among partners) and flexibility (ability to take a fit-for-purpose design and adjust as needed over time). My theme is "like rock, like water," to reflect both aspects. I like to project an organic view of partnership design, and most images on my website are rock piles, especially with water coursing through. http://www.structuredpartnerships.com This organic perspective also fits my view that partnerships are by and about people, not just abstract structures. My advice is geared to "sustainable, efficient and impactful" partnership programs. My target audience is primarily the partners themselves (like government ministries / agencies, multilateral organizations, NGOs, private sector), as well as academia, supporting lawyers, policy experts, accountants, etc.
I have uploaded a word document that collects a number of logos that I like. Not all may be appropriate, but the style part that works for me is something smart or whimsical, not too fancy but a little artsy, clear text (Structured Partnerships is important) with a visual message as an add-on or accent. Preferably with some color - text can be black, but at least color in the picture.
