Does the LLC own any of the IP? If it was set up correctly, it would, and you'd need to work with an attorney to convert the LLC to a C corporation. There's no online service I'm aware of that can do that safely.

When you're issuing yourself shares, you can have the attorney make the start date of the vesting backdated to account for the work you've already put in. E.g. you can backdate the vesting start date to a year and half ago.
