Hi, this project looks really interesting but unfortunately it can't be done for $3,000, not just by our team, but nobody can do this, since it is 600+ hours project.
So, if you want to avoid possible problems and save your time and money, and to get your project done on time and budget, we can discuss more details.
Also, we will share some useful info with you that will help you to manage this project no matter which freelancer you will hire for it.
When we could agree some chat meeting and talk about your project?
Best,
Slavko, Alfabit Team
