    It’s very hard to convey what you’re looking for. There was really very little creativity. I kept asking for something and he just wasn’t getting it. Its just his level of expertise that’s all. If you need a simple cheap idea, then try it. I personally would not use again.

    Took 5 revisions, most of them were due to small misses like not providing the requested files, small quality issues, uneven spacing, etc. A lot of time and back and forth was needed to get to the final product. I hired another designer to do the same work and they did it with only 2 revisions and higher quality.
