Businesses can purchase a space for their business card, here. This is used for recommendations of services to authors. If you require an invoice before making the purchase, let me know along with the email address of your business, and I'll send you one via PayPal. Note: A one-time purchase of $50 (US), places the card on bulletin boards on three sites, Amy's Bookshelf Reviews (https://writeramyshannon.wixsite.com/bookshelfreviews), Genesis Book Promotions & Blog Tours (https://genesisbookpromos.wixsite.com/genesisbookpromos)  and The official Blog of Amy Shannon​ (https://writeramyshannon.wixsite.com/amyshannonblog).
