Filipino preparing for work in Da Nang

I'm preparing for a work being a graphic artist and a photographer at a certain resort in Da Nang. The reason I learned about the job is that a Vietnamese friend of mine shared it to me last 2 weeks. It went fast. I sent my resume last week then yesterday I got my initial interview. So far, I think it went well. As someone who has already gone to Da Nang, I think everything would be more than fine. The place, the people, weather, everything! I can't wait to be there once again.

Just that...

I'm thinking about how can I get to the Da Nang without going through a lot of process in the papers and all. I just don't know. I wasn't recruited by an agency or anything. I've been hired directly by the company. I don't know. I'm worried about the visas, requirements, work permits, bla bla bla.. What kind of process shall I have to go through? I'm pretty sure it won't be like most of the OFW's. What shall I do? I want to be there as soon as possible. Maybe in first week of July. Please help me! Thanks in advance!
