Sign, Sign,Sign, Most of the companies have a sister company that you are not refered to until you have proven yourself with the smaller shops. It was about 1 year into the business when I was called by companies that I had applied to that paid big. Now I get phone calls at home from all kinds of companies requesting me for jobs not posted on the board that are in my area. And once you are established you can also ask for increased fees or bonuses. On Saturday I worked 4 jobs all were less than 45 minutes each all within 15 miles of home and made 145 not bad to 3 and a half hours work. I try and sign up with at least 10 new companies a week.
A tip is also at the end of the month the shop fees are sometimes incresed or have a large bonus to get them done by ther deadline. I see a job and know it will be up again in a week or 2 and wait for the fees to go up before requesting it since you can not do the same location for quite a while.
