If your just looking to swap in and out you can use Houdiniswap
Discussion
Careful with Houdini Swap. Maybe they're legit, but you have to trust them since they know both sides of the swap.
Monero Talk podcast did an interview with them about a year ago explaining how it works and other details if you guys are curious:

If you want to turn up the paranoia dial better to do Swap#1 on 'Exchange A' and do Swap#2 on 'Exchange B'
1. Let some time pass before you do Swap#2. Maybe a day or two. The more time the better. (resists timing analysis)
2. Don't swap it all back in one shot, break it up into a couple chunks (resists amount analysis)
3. Get behind Tor or at least a good VPN. Change Tor identity or VPN server for each swap.
