Doesn't matter how many contacts there are.
Setup a table for companies and a table for contacts, with a company_id foreign key in the contacts table.

Something like:

create table company
(
      company_id int primary key,
      company_name varchar(255),
      company_Address varchar(255),
      Main_Number int,
      Industry varchar(100),
      Website varchar(2000)
);

create table contacts
(
      contact_id int primary key,
      company_id int,
      contact_first_name varchar(100),
      contact_last_name varchar(100),
      phone_Number varchar(100),
      email_address  varchar(100),
      contact_address  varchar(100),
      contact_city  varchar(100),
      contact_state_province  varchar(100),
      contact_country  varchar(100),
      contact_postal_code  varchar(20)-- ...etc...
);


ALTER TABLE contacts ADD FOREIGN KEY (FK_company_id) REFERENCES company(company_id);
