The only way as far as I'm concerned to get something like this done is to separate it into several equally important facets. Fitness, recovery,injury prevention, time management.
Fitness is self explanatory, I'm guessing you're fairly fit due to your business and not necessarily just running fit, your mileage isn't high but I guess you cross train too? For what you're planning on doing I'd build in several day back to back runs after increasing your base fitness for the next month to six weeks, try to get your weekly mileage up to about 50 miles per week then introduce longer back to back runs declining in distance but increasing over the weeks, i.e week one fri/sat/sun 10/8/6 then increasing the distance slightly over The coming weeks.
Recovery is also self evident and in tails into injury prevention nicely, if you don't already start both a stretching and a strengthening regime now particularly concentrating on the core muscles, hip flexors, max and minimums flutes, adductors. Rest well when you can and get regular sports massages. Foam roll after every run religiously, drink recovery drinks to replenish energy stores
Time management is the one that's going to be difficult, you say time isn't an issue but it's difficult for anyone to set aside a minimum of two and potentially three hours a day to run. Be prepared to listen to your body and run only when you feel ready. If that means cancelllingr a morning run and trying to fit it in later in the day so be it, you'll have a mich better chance of success if you do
