I, at least in my opinion, offer an reasonable price for the job I am assigned to. I try to offer a price that is fair, because before I was a person who worked for a company, and they always undercut the employees. I know how much the company pays, and I know their prices, so with that knowledge, I can also offer a reasonable price for me and the customer.
Before this, I’ve worked in companies, so I have years worth of experience. I’ve also experienced “problems” with my work, and if I were to finish a job with a customer, and something happened to the work, I would know what caused it, and of course fixing it afterwards.
One of the main things in my opinion is how much they’re willing to pay. I offer a good price, depending on the work.
