Hi,
Hope you are doing well.
Your project seems interesting and fits with respect to the expertise of our group. However, currently, we will be involved with a couple of projects for around 1 week. Then we can concentrate on your project. We are positive that it won't take more than 10 days and won't cost more than $150, yet it might vary up to $200, depending on your time limitation.
If it's reasonable for you, we will let you know about the accurate estimation very soon based on your time limitation.
Finally, for your information, our group has more than three years of successful teamwork experience in a variety of projects. We will stay with you until fully satisfy your expectations.
Best wishes,
Zada Group
