Package deals only sell if they are heavily discounted. Otherwise, most people can't afford everything, and very few come here to set up shop from scratch. (One-Stop tuba shopping is not really a thing.) Also, package sales force people to buy stuff the don't want or need to get the stuff they do want or need, and the larger the package the more likely you will have potential buyers walk away because the things they do not want outweigh the item they *do* want.
I would list each instrument with its case or gig bag in a separate post.
You need to read the red text block at the top of the For Sale page to make sure your ad conforms with the site's rules.
After your horns are listed separately, I would list all your accessories individually within a single post, offering a buy-it-all price with a realistic shipping quote and then individual prices if you want to go that route. (Personally, I would do this for sheet music, too, but I would sell books as one buy-it-all block and sheet music as another. I would not sell and mail each piece separately or you will be doing this for many months. Either way, shipping or postage needs to be paid by the buyer and not you or you will end up losing a lot of money in the end.)
There are other places to list your gear, too. Facebook has several tuba/euph-centric selling groups, but I have not had luck with them. Reverb is excellent, like a high-end eBay for musicians. And
TubaForum is a small but very active group that also has a great For Sale forum. Both TubaForum and TubeNet are likely your best bets for sales as both are free and have very active For Sale forums. Sign up at the other place and post your ads here and there at the same time. There are no fees to join or to post ads in either community.
Finally, you seriously need to make the effort to take clear, well-lit, high-resolution photos, and you need to host them remotely, like on
Imgur, or
Flickr or some such place. You have to copy and paste each photo's actual URL and then tag them individually. It sounds harder than it is. (I used the same type of tags to display these names with embedded links.)
For photos only, the tags are like an on and off switch to display what is between them as an inline photo. You use the brackets ( this [ and this ] ) to enclose the tag "IMG" for the opening tag, and then "/IMG" for the closer. I will post a photo below. To see how this works, click the " button in the upper right to get my message to display in a quote window, and you can then look at the image address and how it was tagged. It really is easy once you have your images hosted and have their addresses (URLs).
Note that the image you want to post must have a URL that ends with the image type, like ".jpg" or ".tiff" — otherwise you do not have the actual address of the image but some other address that only points to your image indirectly. It must be the actual image address. Here is my example. Quote this text to see how the tags work.
The two hosting sites I listed above are still free, but require you to sign up. They are legit, though, and very commonly used here.
