Modify the template urgent

I need to transform the area "user1" in two columns to put two modules side by side. I've tried everything and the second module goes to the bottom instead of being next. How can I change the template? Thank you!

This is not easy to explain. Custom work will be needed there for additional price. If you are interested, you can send private message using "Report to Moderator" and one of our moderators will contact you.
