We use our own hosting and design. Wix is a pretty poor choice in my opinion.
The faith based idea is fine. Not my cup of tea, most companies around here that push that do not succeed long it seems.
I would find a professional designer for the logo, you say you did, I would find a different one. There are several on this site and many more not on this site. You may spend $1000-$2000 or even more, but small investment for a 20 year old business.
I'm not trying to bust your chops, the logo and character do not say sign shop to me at all. The customer will not know what the tools are on the belt even if they can see them to tell what they are, the paint brush would indicate you specialize in hand painting.
