Dating Site Modifications

Hi, I have a dating site that hasn't been launched yet. There are 112,000 members on the database though - part of an exchange so they can meet as many people as possible. Like I said though, they don't know they are on the site yet as it hasn't been launched. Before I launch the site there are a few errors I need fixing/checking because unfortunately there have been many bugs in the script which I've had to ask the company to fix, but it seems never ending. I always find an error and so I am not very confident now that when I launch the site people are going to run into errors and the site wont perform accordingly etc. The things I need doing are: Checking the Search - to see if it works properly when information will be on peoples profiles and that there are no mistakes/bugs. Rearrange the 'edit profile' page for the user so it looks the same as when other users view the page (but obviously with the necessary edit buttons). Set all current and new users alerts to 'on' by default (so they get emails when their profile is viewed/messaged etc) because right now the default is to have them 'off'. And to point out to me any other bugs/errors you find. The script is pg datingpro. My budget is not huge since i've have already spent alot of money on this site and so don't have much left. The time scale - as soon as possible. Thanks alot and let me know of any questions.
