Chosen prefix collision attack against MD5

I need some collisions in MD5 hash for strings like these : First string : HEAD/dSbE5HVmhPRE16Wm1Vek5HU MD5 : e10ed23a44d6dc79974e01a6eae68122 Second string : TAIL/d1l6QmpPVGt5T0RCaU9Ea3h MD5 : d41cc0018217b1d0042cbca9acad53e6 In other words i need two strings containing your custom characters in this range ( [A-Z] [a-z] [0-9] ) with these two prefixes ( HEAD/ and TAIL/ ) and the length of strings should not be more than 28 , just like the samples above . The next feature of these strings is that they should give us equal MD5 hash code. As you can see the hash codes of the above strings are not equal. I will pay for every two strings with equal hash code that you can find for me.
