We have been working on Freshbit's over the recent months.
The service will feature a familiar function for users who have used Helix Light by Grams.
Registration will not be required, Fee's will be low in comparison with Helix's and payments for clean address's will have unique transactions with none sent out together with other address's paid from our service.
An announcement will be made next week with more information after final testing phases are complete.

You should PGP sign all deposit addresses and maybe some data about the transaction as well. It'll encourage you not to scam, give users mathematically verifiable proof if you do start scamming, and it'll make the users feel safe in knowing that your ability to scam is severely limited.
Maybe sign something like this?
Also, how do you plan to give people truly clean coins? How can users be assured that coins they got from a relatively minor crime like shipping out a couple grams of weed here and there won't be traded in for coins from a much more serious crime like shipping out guns? (And please, if you're going to answer this with something stupid like "we can't divulge any info about how your coins are actually made clean" then don't answer the question at all. You're making a bold claim saying that the coins will really be clean, and it's important that you can give at least some info about how that process is done.)
