Hi e-win.gr,
As mentioned in our sticky thread (http://wordpress.org/support/topic/welcome-the-events-calendar-users-read-this-first), we unfortunately are unable to help with with customization, styling or integration issues not caused by bugs with The Events Calendar. You have a few options:
1. Check out our extensive support resources and try to figure it out on your own: https://tri.be/support/ & http://tri.be/support/forums
2. Hire a developer to assist you. We’ve got a list of freelancers who know our code and who we can vouch for. Email us (pro at tri.be) and we’ll pass that list your way.
3. Purchase a Pro license to get more support: http://tri.be/shop/wordpress-events-calendar-pro/. As mentioned in the sticky thread, we can provide both a deeper and more frequent level of support for PRO users.
I hope that helps and good luck!
Cheers,
– Jonah
