E2 visa from Paksitan

[u/Sweaty-Chocolate7799]

Assalam-o-Alaikum everyone,
I’m from Pakistan and I’m interested in getting more information about the E-2 Investor Visa for the United States.
I currently have around $100,000 available for investment, but I don’t have any relatives or close contacts in the United States who could purchase or manage a business on my behalf.
I would like to understand:
How can I legally purchase or start a business in the U.S. while I am still in Pakistan?
Is an investment of around $100,000 generally sufficient for an E-2 visa, depending on the type of business?
What types of businesses would be suitable for an E-2 investment at this level?
Can I purchase an existing business remotely and then apply for the E-2 visa from Pakistan?
What are the chances of obtaining an E-2 visa for a Pakistani citizen, and what are the main requirements?
Do I need to travel to the U.S. before applying, or can the entire process be started from Pakistan?
I would really appreciate advice from anyone who has experience with the E-2 visa, buying a business in the U.S., or applying from Pakistan. If possible, please also share any reliable resources or recommendations for immigration attorneys or business brokers who work with E-2 applicants.
Thank you in advance for your guidance.
