Cisco router bandwidth limit and/or manipulation between two sites

I have a situation where I am splitting a DS3 line to 2 sites.  The DS3 line comes into my Cisco 3800 router on interface Serial 1/0.  From there I have 2 Gigabit Interfaces Gi0/0 and Gi0/1.  I have traffic routing for 1 block of IPs to Gi0/0 and another block going to Gi0/1.  All that works great.  My question is about limiting bandwidth.    The link is not a full DS3, we are only supposed to get 10 megs (although speed tests show 35200 kb/s down and 33332 kb/s up).  My goal is to guarantee at least 75% of the bandwidth to GI0/0 and the remaining 25% to Gi0/1.  If the link is not being used by one interface, the respective interface should be able to use the whole thing.  I would still like to use the 10megs for calculation as I am not sure of the longevity of my current speeds.  
Thank you -

Mmm, perhaps one of the more experienced experts can chime in and correct me here - but IPBASE has very little ability for traffic management - QoS, rate-limit, etc.

You may need to look into ADVIPSERVICES.

I was using the rate-limit command but I was getting very odd results.  The speed test would jump all over the place.
