I accept PayPal, credit cards, Zelle transfers, and US-only personal checks.
For projects $700 and over, a booking fee of $350 will reserve your slot and will be deducted from your balance. 50% of your balance is due before the project begins. The final balance is due upon completion and before your manuscript is sent to you. For projects less than $700, the deposit is 50% of your total.
I issue invoices through Zoho, which lets you pay directly through PayPal or by credit card.
