Hello, my name is Brian Adamczak, I live in the United States (Minnesota) and I'm a new freelancer.com user - so bear with me.
I have done many projects using Bootstrap and I’m certain I can accomplish the task you describe. I'm just getting started as a freelancer, but I've been very successful in my career, and I'm confident I can provide you with the same value I have my traditional employers.
