website developer

Hi Jawad will is be possible to create a financial asset management website platform for me...It needs to be a website that has also had a client user portal where clients can login into user pages and have a personalized dashboard but wont be complicated. You should also be able to show me how to to login to word press and manage or update information showing to the client based on activity in that website at any moment. I have sample websites as examples you will be able to clone but most of them do not have a client login portal which is something you and I will have to communicate to develop. How long can it take you do do a project like this? How soon can you start and what will it cost? Thank you
