Okay, so Peter has account management skills, which are in demand. He also has experience as an owner of his own company, Photosound. This suggests he can handle various responsibilities. Microsoft Office skills are also valuable. Considering his experience and skills, I'm estimating his hourly rate to be around $75. This is a relatively low estimate, as it's based on general account management and Microsoft Office skills. However, without more specific information on his industry, location, or experience level, this is the best estimate I can provide.
