I need a Tax Preparer for my Freelance Taxes

I am looking for a tax preparation expert who can help me prepare my freelance quarterly taxes. This is my first experience as a Freelancer. I work with 2 clients based in Germany, while I currently live in Spain and am preparing taxes as an American Resident. My clients pay me directly to my bank account in Spain and no taxes are deducted then.

I usually use TurboTax on an annual basis, but need some guidance for September’s quarterly freelancer tax deadline as well as at the end of the year eventually.
