Late IRS Form 5472 & Pro Forma 1120 Filing for Foreign-Owned US LLC

Hello, I am looking for an experienced US CPA or Tax Professional who specializes in tax compliance for non-resident entrepreneurs (foreign-owned single-member LLCs). Due to receiving incorrect professional advice, I missed the April 15th deadline for my newly formed LLC (Adelfia Systems LLC). I need to urgently file Form 5472 and the Pro Forma 1120 for the previous tax year. Current Situation: - Single-member LLC, 100% foreign-owned. - The LLC has an active US bank account (Mercury) with transactions, but NO Effectively Connected Income (ECI) / US source income. - This is the company's first year, and the filing is about 1.5 months late. What I need: 1. Preparation and electronic/fax filing of Form 5472 and Pro Forma 1120. 2. Drafting and attaching a professional "Reasonable Cause Statement" (Penalty Abatement Letter) to accompany the late filing, ensuring protection against penalties. Please apply ONLY if you have proven experience with IRS penalty relief / reasonable cause statements for late Form 5472 submissions. In your proposal, please state how quickly you can complete this and your fixed fee for the entire service. Thank you!
