Online Game Design/Development

We are looking for someone to design and build a web-based word game. The branding already exists and simply needs to be adapted for digital presentation. The game rules are relatively straightforward: the players are given a sequence of letters such as \"UM\"and a timer starts. The first player comes up with a word containing this sequence such as \"THUMB\", then the next player has to come up with another such as \"CRUMBLE\" and so on. Each game lasts a random amount of time, anything between 30 and 90 seconds, and the player whose turn it is when the buzzer goes is penalised with a point. The winner is the player with the least amount of points after 13 rounds. There are some refinements to the game but this is essentially it. The AI needs to ensure that the words players come up with are within the rules of the game and also, of course, legal, requiring some form of built-in dictionary. Ideally, the game will be playable both solo, ie against a computer opponent(s), and against other players online. At this stage we are looking for people with relevant experience who can show an appreciation of the concept and represent good value as the budget is limited.
