Logo for Charity - PlayDough Project

I am after a modern style logo for the charity that I am working with. They are called the “Playdough Project” and use's the acronym “PDP”. They are an organisation that works with kindergartens in disadvantaged parts of the world and donates both time (They are qualified teachers) and also resources from the money raised to help with the children’s education and learning. I am after a fun logo that has both silhouettes of children similar to the logos attached, as well as its own unique feel. Initially I am after 3 or more different logo concepts from you, which we will then shortlist and work with the logo of our choice. Currently the primary colors are blue, green, white and dark grey. But if you think the logo might be better by making it more colorful please do so as we are not set on the colors for the branding yet. I will be after several revisions as I want to make sure the logo is correct and up to standards. The completed product is to be delivered in vector/ai/eps format, so that we can use on multiple mediums in the future. As we are non-for profit and doing alot of the work in our free time we do not have a huge budget. Extra Details include; - "PlayDough" is to be the focus and not the word Project. Because we are using the tagline - "Raising Dough for Play" - The P and D both to be capital letters in PlayDough should you choose to use the full word rather then the acronym - Alternatively the typeface could be in all Caps to remedy this. - Do not copy the example logo given, they are only examples and are to be treated that way - Do not use of gradients - Do not use cartoons or pictures of children in the logo on silhouette versions
