ecardone the biggest Liberty Reserve exchanger takes Ukash directly somehow. problem with Ukash is they only pay out once a month, and will sock you with enormous fees as they've already signed agreements with wm-transfer (web money) and don't like working with other currencies, being that they are trying to build a corporate monopoly. the minimum fee to accept Ukash/PaysafeCards/CashU is something like 7%, and gambling and other high risk sites (or e-currency) are typically fleeced with 15-30% fees.
signing a direct contract with Ukash also means you must cash something like min $2-5k a month with them, and trying to just get a hold of a sales rep to register your company is like pulling teeth. if you promise them $10k a month in transactions maybe they will reduce your fees to 7%. maybe. that's not $10k in sales, that's minimum $10k in transfer fees you promise to pay them monthly. this is why there are so many Ukash brokers around, because they can trade around $5k a day in Ukash so are better to work with than Ukash directly.
Ukash was basically invented to facilitate online gambling, you'd have no problem taking it directly then using it to convert into bitcoins in the background for your customers. just find a payment gateway with it already built in and now you don't have to wait until the end of the month, the gateway pays you out within 48hrs sometimes same day. hopefully the gateway you pick does Cash-Ticket (European ATM payments), Russian ATM payments, Alipay (china), and local debit cards too. All non reversible transactions
http://www.paybycash.com/options/ almost all of these are prepaid/non reversible. I have no clue when paybycash pays out to merchants or what their fees are, but they're certainly not the only game around. typical payment gateway will charge you 10% for PSC and Ukash payments.
adyen.com is probably has the most options for prepaid customers, almost every country in the world somebody can deposit money or pay with a local cash card. they work with online casinos, and are based in the EU. just tell them no US payments. they also don't make you sign any contracts with minimum sales, you pay like 0.30 Euro per transaction for most payments, 10-20% for all the card and voucher systems. would be worth it, now somebody in Argentina or Brazil can walk into a supermarket and pay to get into your casino. if you apply to any gateways, don't say anything about Bitcoin. they don't need to know you are exchanging the money into something else. that will just add confusion, most of the sales reps are just drones anyways.
as for perfect money I don't trust them. they seem to be floated by the Hyip industry and at anytime could be seized/disappear or end up bankrupt like Euro Gold Cash went under. you could however as a casino probably sign a direct contract with them that they will buy back the PM wholesale from you at a favourable rate you can then trade into bitcoins.
if you really want to go sketchy, sign up with solid trust pay. they let you do visa/mc transactions, accept 3rd party wires, all sorts of shit. could float a bitcoin casino using them safely.. seems they ironed out most of their problems when they started out
also, this is the reason i'm building my own voucher system, because i hate Ukash/PSC and the other corporate voucher systems. big contracts, high fees, no way for small biz to get in. this voucher specifically geared towards cryptocurrencies payouts for merchants
