Logo design for the site

You need to design a logo for the site for a small fee. The fact is that when they ordered a site with a new design, they developed a new logo for us there, but alas, they did not want to provide the source code of the logo, in other words, as did the entire source code of the site. They've made an unrealistic amount of money for this.

The logo design for the site must be made necessarily in CorelDRAW, and the font (fonts) that will be used when creating the logo must be provided. It is a new idea and creating a logo for the site from scratch, since we were warned that if we copy the logo for any other printed products from the site, it will be “not good”.
