I will do it for $100,000 USD, the reason why is because I have already developed something similar to it, much better than what you will get from anybody else for a price tag lower than $1,000,000 USD. Anyone who bids at what you are offering, is either an idiot who does not understand what he is doing or does not know what to do. This requires development of deep learning software with neural pathways. Historical modelling of sentiment to establish benchmarks and training a AI on it and using that to develop a self-correcting regression model scaled on correlation basis to -1 x 1 where 1 relates to strong keyword match for sentiment of stock movement, you then need to factor in the existing price movements of stock, and then further factor in time evaluation (lag between sentiment and price). You will also need to automate it and get parameters for data scraping, you would think company name would work... Nop. After developing this you will need to then use the model to integrate into Quant relations, as you will come to realise, stock price is not the best indicator for anything more than 6 months, and a better indicator would be its quants. Ofcourse you can ignore it if you only want short holds of a week to abuse trends... Also your output of buy and sell is too basic, you should have an output of possible recommend for long/short positions with corr, then you further analyse it based upon other markers and then short/long. You seriously should do more research.
