We now live overseas and are looking at converting 401k, 403b to IRA.

What range of fees would reputable providers charge for this service?
When you pick a company for your IRA, they should have information about rolling over funds from another IRA or a 401K. They will be able to walk you through the process.
There shouldn't be a fee for doing this. They want your money to be invested in their funds. Once your money is in their hands they are able to generate their profits.
You will want to do a direct transfer. Some employers will work with the investment companies and send the funds directly to the IRA. Others will insist on sending a check to you. The company that will have your IRA should give you exact specifications for the check so that you won't have to cash it. The check will be payable to you or the IRA account. The IRA company will have all the details.
Decide if you will be converting non-Roth to Roth, before doing the rollover.
