Well, first of all.
It would be nice if you have a portfolio, a more professional profile (you know a picture, a small description, maybe a link to your work or contact information). Remember that claiming you do something but having no samples, no free to read content for anyone to check out it's the same as having nothing. Ideas or projects that are on the making, works in progress are one thing, something that has been published be it independently, online or printed is another, since it can be considered a finished product.
A lot of people either have free to access Documents files, folders, PDFs through Google Drive or other media hosting platforms that I believe that with the access to internet you can even google and probably even find hosting platforms that can adapt to your needs.
What genres can you work with, where do you expertise, not to mention that first it's important to mention that in the Tapas Forum we're not allowed to create threads offering our services or promoting sales, we mostly have to wait for someone to create a thread, and if it's paid, you offer yourself there.
Remember as well that Grammar, understanding format and other aspects is also important. Take the time to properly write your inquiry, edit your main thread asking everything you need to know or maybe looking for advice from other Writers before doing things out of impulse
