Series 7 firms

Could someone pls list some firms that require series 7 and will sponsor? Also, approximately how much min deposit will those firms require?

 

Bright Trading

 

Also Echo and Hold....Along with Bright all great firms

 

Thanks.
I am aware of Bright, Echo, Assent, Hold.

However, I found them to be a little expensive for someone that trades <1m shares. How's the commission at Hold?

Are there any others?

 

Careful with Hold.

 

elaborate?
