请假，以下律师收费在合理范围内吗？

在网上注册了个人信息，寻H1B及绿卡申请的律师。 今天收到一律师回信，收费如下：
Fee Information
Consultation: I am willing to offer an initial consultation of 30 minutes for $200.
Fee type: Learn more about lawyer fees
FLAT FEE The total fee that I would charge for this case is $3500.
Fees are due in installments.
Other fee information: This response is negotiable and subject to change upon further information I learn from you.
该律师来自Azulay, Horn & Seiden, LLC，据说是全美第四大律师事务所。

本人为新手，对此毫无经验。寻求各种建议，先谢了。 另外，我在芝加哥地区。
