Suzuki 2 Strokes

Greetings,
I have a 76 750 that has not been run since 1995 with 21k on it that needs some engine work ie. crank seals and possibly some mild porting. Every thing works: spins over, has spark etc. Can any one provide a one stop source that might be able to accomplish this? I am looking for engine work only. I will be restoring the remainder on my own.
Thanks for your input.

Would help to know what part of the country you are in.

Western slope of Colorado, (7200 ft. msl) hence, the need for some mild porting and the correct carb jetting. I made contact with Jemco and digested a lot of info from this forum, so I see the need for shipping. I would like to get the logistics worked out to limit the complexity with a project such as this.
Hope this helps.
