We believe the customer is always right. All work we supply can be re-edited to your requirements. We will work with you to provide the result you want. According to the Berne convention, all work is copyrighted the moment you own it. It is still advisable to place the verbal notice of copyright on a page with your logo printed.
Trademarks are expensive.
We believe that trademarking your logo is money well spent. Post this to yourself as registered mail - without enclosing it in an envelope. Obtain a receipt. When this item arrives you'll need to sign for it. It will have the date stamped over it, which will prove you owned it at that time.
