You can store the brandIs in a different table and store their curresponding ids in the Client table

Table  Brands (BrandID int identity, BrandName varchar(120)  )
Table  ClientInfo (ClientId int, BrandID int )

You should create a new table with the customer ID and the brand. Then you make a inner join to get all the brands for each customer.

Three tables ....
Customers (CustomerId, customersName, etc)
Brands (BrandId and BrandName)
CustomerBrands (customerID  and BrandId)
In the Brands table you will have all the brands available and in the CustomerBrands you have a list of all customers and the brands they have. Then you can use a INNER JOIN view to show all

SELECT Customers.name, Brands.BrandName, Customers.customerID
FROM   Customers INNER JOIN
       CustomerBrands ON Customers.customerID = CustomerBrands.customerID INNER JOIN
       Brands ON CustomerBrands.BrandId = Brands.BrandID
