Look into IT helpdesk. You might have to go through a temp agency to start, but everywhere needs IT and customer service work is directly related to a helpdesk job. Entry level stuff often doesn't require anything beyond customer service experience and proof you have basic computer knowledge. Great way to get into a white collar job. Plus you feel like you're achieving something each day if you're deploying equipment, instead of losing your soul working in Excel. After that you can get IT certifications and jump off to something better.
