Add Data to Wordpress site & a few modifications

Hi, I have a wordpress website that uses BuddyPress and rtMedia to create user profiles. I have a large database is CSV format & pictures that needs to be added to the website. Its not just a simple task of converting csv to sql and uploading it. You will have to create a dummy account and study how the data is getting saved when an account is created and all the new data in the same manner. The data should be added perfectly as if a new account was being created. There are also pictures to be added. Pictures are named to link then to an entry and there may be several different pictures to be added to the same account. In addition several size versions of the picture might need to be created to be added to the website. This is all part of the project. The database is very large 125,000 different accounts and several pictures per account. So I want to upload the photos to amazon S3 to save space on my server . So I will need the script modified so that these images are displayed from amazon s3 vs my own hosting. This has to be done only for the data I give you to add to the website. If a new member signs up for the website it should function as it currently does and store the uploaded pictures on my own hosting. A few other modifications are also needed: On the homepage it displays the number of members online, # of men online, # of females online. I want a random base number set, so it never looks like there are 0 people online. So for instance the rules should be 1) # of men online (random number between 100 and 200) + number of men really online. 2) # of women online (random number between 150- 300) + number of women really online. 3) # of members online = the sum of 1 & 2.
