Price for 3 flash applications

I have developed 3 flash applications for a website. They are not completely finished yet but a large part of them is done. I have presented the applications to the buyers and they liked them and they want to buy them. The problem is that these are the first flash applications that I am selling and don’t have that much experience concerning the prices. I have uploaded an archive with screens from all 3 applications in order to ask your oppinion on the prices I should ask for them. There are a total of 18 screens (because of the number of the pictures and of the size of the archive I couldn’t upload neither the pictures nor the archive here on the forum). I would like prices for each application and a total price for all 3 of them if this would be different from the sum of the prices of the each. Pls help !

All 3 are for a sports newspaper website.
The first is a application that shows advanced data about an important football (soccer) match: live comentary, information about weather, attendance, stadium capacity, stats, tactics, images, videos and others.
The second is an application that shows live football results. Here you have the option of selecting your favourites and move them on top in a myMatches section.
The third is an application for viewing soccer charts from countries all over the world.

On another note I would like to ask about the functionality of them. Should I make the data load from XML or a database ? My option now is for XML because I am not loading that much content that would require a database.

Thx ! I am waiting for a response as soon as possible !
