I'm starting out in the electrical estimation career and have been advertising on Facebook to find work and learning opportunities, but I haven't received any responses so far. I'm thinking of offering free services to attract clients. Since you're experienced in electrical estimation, how big is the market for this career? Do most electricians handle this themselves, or is there room for dedicated estimators? Based on what you've seen, do you have any suggestions or guidance for growing my business, including things I should watch out for and ways to increase my opportunities?
