I am always asked by clients for recommendations for different kinds of service-providers and products, so I decided to keep them all in one place. After over 5 years in business and several hundred clients (with various requirements and experiences), I've made a list of people and services that I know and trust, and will recommend without hesitation.
Siteground - Get 60% off. The best customer service, with 99.9% uptime and really fast servers. At their price point, it is hands down the best. I only have good things to say about them, and I've worked with over a dozen hosting providers either for myself or for my clients.
WP Engine - for enterprise performance, these are the experts in managed WordPress hosting. A bit pricier, but they are very reliable, and lightning fast.
Studiopress - The foundation for all my themes, Genesis provides exactly what you need to build a secure, SEO-friendly, powerful WordPress site without the bloat.
Sridhar Katakam - a membership site full of useful tutorials for customizing WordPress and Genesis.
Genesis Explained - this book will be your bible, if you want to learn how to create child themes for Genesis.
For capturing those email addresses. Now that Facebook and Instagram are changing their algorithms, mailing lists are ever more important.
Mailchimp - so easy to use and integrates well with Genesis themes. The starter level is free.
Convertkit - I have personally not used it on my website, but I have several clients who swear by Convertkit.
My Fonts - the best source of premium fonts. Almost all font foundries are in their library.
Creative Market - Most of the newer font designers are selling on Creative Market. It is now the best source of calligraphy and handwritten fonts.
Font Squirrel - legit source of good quality free fonts that are licensed for commercial use.
Some of these are affiliate links and I may earn a small commission if you sign up. However, these are products/services that I will recommend without reservation, regardless.
