What would be the best way for me to get into Pro Challenges?

Starting from scratch is really hard. You can get a photo resume along with highlights of your career (multiple copies) and send them to the marketing dept. of would be sponsors. Another way is try and get about $1,000 together to try and buy an agent in this Field who might have the right contacts to help find sponsorship.As a last ditch effort you could mail your resume to car owners and team owners...you just never know who will help. Make sure to let them know your pion for racing. Good Luck...I wish you well
