Advise on 9 month profit maximisation plan

Completely new to investing and have no clear direction on where to start from. However I wish to maximise profit in this 9 month period as I have important projects to undertake afterwards. The plan currently is to set aside about 1000 pounds monthly and invest it into a low - medium risk endeavour with good turnover, and see where I'm at after 9 months. I'm not sure what a realistic projection is, but I'd like any advise on what to do or where to start
