Don't Choose Based Solely on Price
The lowest bid isn't always the best value. Consider experience, quality, and reputation along with cost.
Don't Pay Everything Upfront
Establish a payment schedule tied to completion milestones, never paying the full amount before work is done.
Don't Skip the Written Contract
Always use a detailed written contract that protects both parties and specifies all terms and conditions.
