## Common questions.



## What makes a useful contractor request?

Include the quote, scope of work, materials, timing and payment schedule. We can ask about the total price or alternatives that keep the work you care about within reach.

## Can we change the scope instead of cutting the price?

Yes. Ask about different materials, a phased project or a flexible start date. Keep any exclusions, changes and payment milestones in the proposed agreement so you can compare it fairly.
