The design of a logo has to completely mirror the company's attitude and legacy. I have experience doing logo designs for clients, with in depth knowledge of their institutions ideals and work process and their outlook in the industry, and bringing out those features and epitomize them in the form of their logo.
I do my research of the institution before starting on the design so as to bring credibility to the logo.
I work in illustrator and photos hop for the logos. The output would include the complete work files for your further use.
