License for a sports club needed?

I wil use the rotate player for the new site of the schmalfeldersv.de ( a beta version of the new site you will find under ssv.dascheberg.de) to show our sponsors. Indirect I will get money from them, but I didn't sell something. It is a little sports club in the little village of 24640 Schmalfeld / Germany. Thanks for a short answer.
