Welcome to the site Candace.
If you continue to do research on this site for your various questions, you'll likely find answers that might put you closer to being able to focus on specific bus candidates that will fill your needs.
The real work begins after your purchase, and is not for the feint of heart or persons that are not comfortable around power tools. You'll have that part covered, so it seems!
It would be cost prohibitive for most folks to have to pay for outside help for the conversion process.
And that's one reason it takes such a long time to complete one of these skoolies start to finish, as the work force tackling the project is typically limited to one or two persons.
In turn, who may or may not have ever actually done such a conversion project.
Don't be discouraged from anything I've mentioned, simply keep in mind it takes time to find the right bus to convert, and it takes time to do the actual conversion.
Good luck, and post pics if you actually do get into the hobby...
