Hello Andres and a good day to you too.
While it´s rumoured that staff may read the one or other category on the forum like Bugs and Site Suggestions, and sometimes post or are seen in the one or other News thread or such, this is mainly a peer to peer forum, and when you´re posting here, chances are you´ll ‘only’ get replies from other sellers/buyers.
Fiverr does support all ways. It´s all there, just look at your main page, top menu bar, footer links and you´ll find.
People/companies can browse the seller´s gigs/services and pick and contact the seller or buy a gig right-out, or they can post their Requests in the Buyer Request section (main page > Selling > Buyer Requests), you should be able to see the relevant posts for your gigs (Gigs are your offerings of services/products to buyers) - but I can´t see any gigs on your profile page though, so… if you haven´t created any gigs, you won´t be able to see any Buyer Requests relevant for the categories you´d have your gigs in.
Once you have created and ‘published’ a gig in, say, logo design, with relevant tags, you´ll have it in the logo design category and will see Buyer Requests for logo design, if you have a gig in the SEO category, you´ll see relevant Buyer Requests for that category, etc. (you´ll unfortunately see a lot of seller´s ads there too, which is not allowed, though, and considered spam, disregard those)
Here are some links which tell you all you need to know to get started, and in addition, you can make use of the forum for lots of additional info, either browse the categories like ‘Tips for Sellers’ to find what you´re interested in, or use the search function.
