I can steer you on the sort of design you should be looking for in your line of work.
There are a great number of great “off the shelf” artworks & photography I can find then adapt for a cheap good logo.
Or it may be that your current logo just needs a tweak to bring it up to date and professional.
But depending on your needs I have contacts who work in design departments in the national media willing to give you great value on an exceptional ogo, done in their spare time.
If you need to go further with design to say a book cover I have the contacts there too.
