How to ask donors to send bitcoin if they are not bitcoin enthusiasts? Have idea for wonderful service many would want to donate to see happen. Those who donate though know nothing of bitcoin. Google reveals much trouble with bitcoin&lt;->paypal or bitcoin&lt;->creditcard gateways.

Exists any credible and reliable service that does this?

Bitcoiners too small group to expect enough from them, bitcoin system too difficult for non-bitcoiners to donate. Non bitcoin donations undermine concept.
CoinBase says that they hope to offer a method to purchase bitcoins using credit card.

In the meantime, that's not happening or at least not without going through some method like VirWoX (buy SLLs there and trade those SLLs for BTCs).

There are cash deposit methods.  Depositing cash at a bank or 7-11, Walmart, CVS is going to be the fastest and easiest way.
