Adaptable web based fully serviced stock broking site

We require a very user friendly stock and unit trust (mutual fund) investment web site, where investors may drill down into detail analysis, as they acquire more skills and comfort. Instruments will be analysed and presented to investors in a risk/return matrix for easy decision making. Investors may choose to invest as lumbsum or monthly installments based on their selection criteria. Funds will flow from investor bank accounts (not credit cards) to our company, from where it will flow to the Stock Exchanges (9 in total, but expandable) and Mutual Fund Managers (possibly say around 50 per country in at least 7 different countries. Information will be accessed from a large database. Information will flow from and to website to investors/banks/exchanges/fund managers. The system needs to integrate with a secondary analysis system (which still require development). Detail might not be sufficient for a quote, but to my defence we are still in process to appoint an internal it person to provide additional guidance, process and terminology, but i would like to get an idea of what skills and experience is out there.
