In my personal opinion.... Avoid further contact (or rather, avoid further expense) with whoever is trying to charge you money. If, after you've learned some basics, you still want help, then you will at least be a little better informed and know what you need from such people, and can make a good choice about who to go with (as well as what that kind of help might be worth).
Dropshipping should be very carefully considered and researched, because as a frontline seller (that is, taking the end-buyer's money), you will be responsible for just about everything but in control of virtually nothing, so I would not recommend it as your first foray into eBaying.
A solid business will take time and effort to both research and build, and I think the best first steps you can take is by listing a few things you have in your posession, get a feel for the whole process, an idea of what makes a good listing, read as much relevant information as you can find in the site map, on PayPal or any other payment processors you will be using, and spend some time here in the forum - there are a lot of sellers here willing to share good information for free, (some who won't pull any punches if they see something that can be improved, but the info and advice is still worthwhile, though asking for specific good selling products or suppliers is likely to result in a wall of silence 😄 ).
