SMSaj.com.hr extension design

Since November 2013. we started aside project; we developed Android app and decided to provide free sms service for people in Croatia. Project is currently owned by Mirko Katić but we are still developing and upgrading Android applications and optimizing code. Unfortunately we are not familiar with front-end development that much and we lack design skills. What needs to be done is described here in this project [login to view URL] I contacted original authors but they are not interested in work.
