Tax Planning & Bookkeeping Consultation for California Content Creator

Hi! I'm looking to book a consultation for my business partner, who is a content creator based in California. Over the past couple of months, her personal income has grown to around $20k+/month, and we want to make sure her taxes and bookkeeping are set up properly. I'm looking for someone who can advise her on estimated quarterly taxes, bookkeeping, deductions, and whether it makes sense to remain a sole proprietor or consider an LLC and/or S Corp election as she makes more money working with me. We'd also like guidance on staying compliant and optimizing her tax situation. Is this something you have experience with? If so, I'd love to schedule a consultation with you to discuss her situation. Let me know if you'd be a good fit.
