You might want to consider trading options.... If you have a "cash account" options trades will settle the next day and you will regain your full buying power the next day instead of having to wait 2 days for the stock trades to settle.
A second option would be to consider opening an LLC and then using the LLC to open the trading account. This would allow you to have a professional account where the LLC is the "owner" of the account and not you as the individual. This is a more complex way to start your trading career but it should solve the problem you are facing.
Good luck!
