Raising cash idea !!!
One of the main and key solutions is pre-order income.
Let me explain :
Another smallish company decide to release a game however to raise funds issued a pre-order incentive.
Pre-order and pay less now but also get access to Alpha/beta releases. It went down well and a lot of people bought the game and a lot of suggestions were made.
So think of this on hypothetical stance 100 of you loyal followers pay up £20 now to get access to the beta and final game come release.
Thats in theory £2000 towards either paying other programmers/artists to help the project or advertising.
(obviously you have Tax/Vat ect to pay)
-----------------------------
Advertising.
Have you considered approaching some well known youtube game reviewers ?
This wouldn't be an expensive option an could get you a large volume of customers if done correctly ect.
Some online retailer are beginning digital distribution, would be worth asking if they would like to stock your game.
Steam is a major player in the games industry now and are allways looking to add new games so shoot an email to them.
Offer skype interviews with online review companies.
Ok I think thats enough food for thought.
Good Luck
