Since resume and LinkedIn profile development is 100% customized, I stick to an industry standard and request full payment up front.
I'll email you a PayPal invoice for payment immediately following our 1/2-hour strategy session. Once you use the credit card of your choice to confirm your commitment to our work together, I'll be poised to begin my writing magic.
And since I'm super thorough, you can be sure I'll email you a detailed invoice so that you can follow up with your accountant to see whether your investment qualifies as a tax-deductible job search expense.
If you have any hesitation about paying for your investment up front, then I urge you to Google Résumé Relief, as my guess is that if I were ripping off my clients, someone out there would have posted something to tarnish my reputation.
I also encourage you to explore your options with other writers, as I want you to feel as if you're making the right choice when you invest your time and hard-earned money in your kick-a** career.
