Having obstacles in your career is completely normal. Tell the hiring manager that you are accustomed to overcoming obstacles and the type of objections you are used to facing.
"The most common obstacles that I have found myself having would be objections on time and price. I find that these are the two things that people are least likely to want to part with. I overcome these objections through creating value in the product and displaying to the client, right away, that it will be worth it for them time wise and financially to give me the time out of their schedule."
