Looking for a dynamic legal brand

Bekar won my design contest for a brand package. The designs for the logo and letterhead were easily approved and he provided the required final files for these two items. We worked on the business card and finally agreed upon a design. The envelope design was a nightmare! Bekar seem to have no concept of what a USPS #10 enveloped looked like. For instance, designs with return address in the upper RH corner (the postage area); logo in addressee data area, etc. Sent him a USPS #10 design template. The final design was almost complete, except that the logo still overlapped the address area slightly. Ahh! The facebook cover page. The initial design started at the edges with a nice blue hue with a gradient that ended with a hideous puce green in the middle. I spent the time describing why I didn't like the message this was conveying. Even though I told him NOT to use green, all subsequent revisions exclusively used green. I final told him to just drop this item from the project. I could do better myself with clip art. Before the design turnover phase ended, I asked Bekar for the required design files for the business card and envelope, i.e., an editable file (i.e. AI), a vector EPS file in digital (RGB) format; a vector EPS file in print (CMYK). All that I have for these items is web preview file, PSD with a 300 x 300 resolution. Instead, Bekar let the clock on this phase run-out and collected the contest design fee. I fault Bekar for failing to deliver all of the required design files; and I fault 99Designs for release payment without a check that source files are present and marked as "final". I sent Bekar a private message asking him to cure these problems before I posted this negative review, but received no response.
