Hi, welcome to the family 
You can find some useful info in these threads:
Trouble selling - this is a great read with amazing info from some amazing breeders.
Company name and logo opinions
You can pay a artist to put you one together, we actually have one or two on here that may reach out to you through messages.
You can download a logo making app, but these usually have some hidden fee somewhere unless you are paying for a “premium” version of the app.
Or you can download some drawing software and have fun. I made mine on Autodesk Sketchbook which is a completely free app on the Play Store (I’m not sure about other app stores)
