GoToSocial is probably the best way to get yourself onto the fediverse at the lowest price possible. It's an excellent choice for solo instances and enables you to migrate both to and from Mastodon.

FediHost has GoToSocial in beta for free if you want to try it out. Simply create a fedihost account and request access to the beta program by emailing support@fedihost.co
