I have designers working with me, so I can even provide you high quality graphic design works if you want.
I can finish your job from start to end with high quality in deadline.
If we meet and discuss details or provide me project wireframe document, timeframe and budget for the project could be more specific and reasonable.
I'm looking forward to working with you and building a long term business relationship.
