The best way to show clients I am confident in my work and serious about doing business with them is by asking them to fund the 100% project amount into escrow and release 50% project amount from the escrow until the job is completed. Additionally, I know my worth and bid an amount which I feel is reasonable, fair, and comfortable.
I accept payments through Guru Billing and Payment System ONLY.
I also guarantee 100% customer satisfaction when it comes to designing custom and unique logos, so if any changes required to initial logo designs, I will do it absolutely FREE. Therefore, with me you get unlimited revisions (within reason) at no additional cost.
I normally use guru PMB for communications, and find it quite efficient especially to keep record for the complete project conversations and files.
