請假，以下律師收費在合理範圍內嗎？

在網上注冊了個人信息，尋H1B及綠卡申請的律師。 今天收到一律師回信，收費如下：
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.
該律師來自Azulay, Horn & Seiden, LLC，據說是全美第四大律師事務所。

本人為新手，對此毫無經驗。尋求各種建議，先謝了。 另外，我在芝加哥地區。
