Sorry, just curious: do others just trust you and provide their phrases/passwords? Or do you provide paid services?
I mostly help others run the software themselves, and help them to construct appropriate tokenlists or seedlists (using surrogate strings such as "Word1" instead of their actual words) as that is often the most difficult part if you have never done it before, and the syntax can be quite confusing to get right, especially with complex passwords or passphrases. I do not offer paid services
per se, but I have ran the software on behalf of other people before. If you are looking for a paid service, then this site often gets good reviews -
https://www.walletrecoveryservices.com/ - although I have never used them myself and therefore cannot personally vouch for them.
I'd encourage you to try do it yourself first, though. As PawGo says, it is often feasible on your own computer. If you run in to problems, post here and we will try to help.
