I am interested in participating in the contest, my specialty and my professional preference is towards minimalist design which I think is what is looking for. But to know if I am on the right path that you are looking for is a main logo of Ptolemy and sub-brands (Teacher, Leader and Policy) more a set of icons-please if not understood well requested you that I clarify, meanwhile I will be working in the main brand, from already thank you.

It seems you have understood it well enough.

The current budget is sufficiently low for this much requirements.Any chance you would be increasing the budget ?

It's possible but I would have to have confidence that someone would deliver what i need, so a sample or some early ideas would be necessary. They wouldn't have to be too evolved. You should also offer me some idea of what fee you would need.

I would submit the logo first and if you are happy with my quality,then we shall discuss the budget.Meanwhile feel free to check out my portfolio to get an preview of my design style.

you need to increase your budget for better participation
