A problem in the home services space is large, new work/replace jobs usually supersede smaller repair jobs. For example, "fix my deck stairs" is going to probably be much lower on a list of jobs from "build me a new deck". I assume this is because the build a deck job is much more predictable and profitable. How will your service operate for repair work that is unpredictable?

"enforce strict quality standards" - This sounds good but there are also local municipal codes that work has to adhere to, sometimes where a repair job has to bring something up to current code standards as part of the work. How will your service ensure contractors are doing this?

Regarding the quality part, say someone passes the quality test before/after photos, etc. and "fixes" someones deck but it later collapses because of faulty work (using improper screws that can't handle load) and someone is severely injured or worse. Are you legally structured where the liability remains with contractors?
