Design a simple and professional logo for SQill

Develop a simple and sleek logo for a new software product, called SQill. Preferably the logo should contain the name of the product (SQill). We would also like to see different options in colors (no purple and no green). We are also open for additions to the logo besides the letters.

The main target audience for this product is faculty (age group 30-70), therefore we prefer clear colors and a good readable font.

If necessary, some information about the product:
SQill is a Content Management System (CMS) for education in which programs can store their educational data. It will help education (mainly faculty) to manage their curricula and educational planning.

This product is a Curriculum Information System built for educational institutions, starting in the Netherlands. SQill is the source system for educational data and educational development. Within Sqill, all data concerning the curriculum (learning plan of the university) is stored in a structured way, the education development process is supported and this enables the school to continuously improve their education.

Education and curriculum development nowadays takes place in separate word documents and many spreadsheets, what makes a lot unclear.
Still offers the solution for these problems. Within SQill, all documents are well-ordered, well-stored and documents are easy to search. This program is built for teachers because it sometimes happens that teaching material is given twice because teachers have no insight into what colleagues are dealing with. An educational institution is obliged to offer certain curriculum material, with SQill they have an overview of which course materials needs to be given, what more and what less.

In short, SQill is a software product (CMS) built for teachers (universities) for education and curriculum development.
