Hello Will.
This looks promising. I've not come across ANY other services like this in the UK. I've found a small handful of places enabling purchase of bitcoin through the faster payments scheme, but none which offer these other cryptos. Sometimes it's a pain having a bank account denominated in GBP rather than Euros, so I'm glad you're doing this!
If you were to create a User Issued Asset on BitShares, I would probably buy some because I'd like to see you succeed. Your service is good for crypto in the UK, and very convenient for users.
I hope you do well, and it'd be great to see some collaboration between CryptoMate and BitShares.
P.S. I recommend taking fuzzy up on his offer of a hangout if you can
edit: perhaps you'd like to know - looking at your website, some of the prices on the homepage are very different to those quoted when it comes to buying...
