Help Needed: File 2024 Mexican Tax Return (Upwork Income with Retentions)

Hi! I'm looking for a Mexican accountant who can help me file my 2024 annual tax return with SAT before the April 30 deadline. I am based in Mexico on a permanent residency but with no experience dealing with SAT, so I'm looking for someone who could turn this around at a good price.

More info:
During this period I worked a full-time job in Mexico (taxed through payroll, with CFDI de nómina)
Additional freelance income from Upwork (Feb–Dec 2024, and also beyond that if relevant)
I have been sent CFDIs and ISR retentions via Facturify (some at 1%, some at 20%).

I want to:
Make sure everything is filed correctly and before the deadline
Understand about my income from both sources and how the second job affected the first
See if I’m eligible for a refund due to over-retention (which I believe is the case)

Preferably looking for someone who:
Is familiar with platform income and Facturify retentions
Can handle everything for me (login to SAT, submission, etc.)
Offers a low-cost service
Speaks English

Please share your price and how quickly you could get this done. Thanks!
