Hey I can do this as long as the 2 other coins are on the Ethereum network (i.e. ERC20 coins like OmiseGo, 0x, Golem etc....and even other ERC standards if need be). If you need to accept coins that are not on the Ethereum chain then we would have to Oracalize the contract to access a database of coins that have been sent to you (So BTC, Monero etc.). I would likely charge more if it is the latter case. Also you say you do not want a template but for most coin contracts they must have the same functions to fit into a protocol standard (so all ERC20 coins have at least the same functions). I can create most ERC standards but by their nature they need to conform to some template of basic functions. I would be happy to hear more. Please contact me if you are interested

Hello, i'm a solidity developer, i can write your contracts without any template (never use templates). You say that you want 2 coins in the ICO, ethereum contracts can only interact with ether or tokens, so if you want to include another coin like bitcoin, that cannot be automatic. Please send a message for more information

Hello, I've been programming for over 12 years and have experience in multiple languages. So far I've built only simple smart contracts, either for ERC-20 tokens or gambling contracts. I feel confident that I can build you a contract to your liking. However I will need more information before I even accept the project. Thanks, Juraj K.

Hello, An agreement should seal the understanding between two gatherings. This is to prevent a change in contract terms and stipulated conditions thus to demand that it be part of an agreement draw up legal agreement has to be met for that agreement to be completed. I will critically take time to examine the sort of service, the legal implications and would seek to present a contract term favorable to my client first. Regards
