iPhone/iPad + Android Simple Games Developer

Hello everyone, I am making this bid request in order to find ideally a freelancer, not company for a possible long term relationship, for ongoing game development. I am new to this area and i would appreciate if you could send me some fair offers. I understand that is not easy to make an exact offer but i would be grateful if you could send me an approximately prize and then discuss what will be the final prize. The games I'm thinking to have for development are considered very simple, something like turn based board games, static quiz, ... If possible, the core would be written in c++ and the gui in Objective C/C++, so that the game logic could be ported to Android (android game development knowledge would also be appreciated). Usage of [login to view URL] should be necessary to ease the port. Full games data (levels, requirements, imagery, would be provided). I just need a relevant price in order to see if we can start a small project like this. If possible, please indicate previous works done! Thank you in advance!
