Assist with database, exchange rate, etc... on Wordpress site -- 2

I am updating my website using Wordpress template and would like following: 1) Would like to incorporate a similar price chart like found on following property page (under 'Apartment Rates'): [login to view URL] to new property page: [login to view URL] Should be set up so the price chart shows automatically for each property on the site. 2) I would be inputting amounts on the site in British Sterling Pounds and need to show on screen amount in US dollars. Currently I just input the days exchange rate on a page on site and it auto changes the entire site so assume it would be set up like this. 3) Set up database so on home page ([login to view URL]) when a user searches 'find your home', results would be based on available dates, # of bedrooms and rental amount. 4) Misc small changes here & there and can pay by hour for work. Thank you.
