Need DotNetNuke programmer to code 4 modules

My current project is a non-profit online game. Its goal is to immerse players into a fictional story using multiple websites, physical props (like books and paintings) and puzzles. It is comparable to a game trend currently known as an ARG (Alternate Reality Game). Each player is directly involved in the story development and obtains points when he/she makes a certain desirable decision (solving a puzzle, finding a clue, etc.). These points are the way to evaluate a player’s performance, but can also be used within the game universe, transferred from player to player (to bribe someone for example), be used to buy hints, purchase items, etc.

All the modules dev. information is included in the PDF found here:
2and2is5 [dot] net [slash] modules.pdf

If possible, I'd like everything to be coded in vb.net since I know no other language than this one. Although, c# would be acceptable if you REALLY can't live in vb language

I would like to receive the quotes via email : vincent [at] twonoses [dot] net

Please bear in mind that I'm a part time student, part time employee and this project will be non-profitable, so I'm paying from my own pocket. I got some quotes ranging from 500$ a module up to 5000$ which is, as you probably know, out of my league.

I'm not short on time (there is so much to do for this project) so time frame could go up to 2 months.

Feel free to quote only on one module if you want. I'm looking for someone who could do the whole job (easier to keep in touch that way) but if you prefer to hand a price for each and every module instead of the whole work, be my guest!

Cheers!

Vincent
