I would say you are probably looking at mid to high $xx to low $xxx....and here is why.
1) Good industry use
2) Easy to remember therefore it should have good name awareness
3) 13 char. is length is good. I typically like to see a range of 0-12 char.
4) Ultimate .com extension
5) Strong keyword of repair. Looks the the most popular are "credit repair", "auto repair" and "computer repair".
6) Unique name but success will depend on development.
