How to launch an aggregator (startup)?

Question

Books

Good day.
I'm not sure if the question is appropriate for the current resource, but I think there are people here who have come across this.
Having gained programming experience, I decided to create a small, my ownproject on a modest budget. The theme of the site is banal - an aggregator of someone else's products. If I somehow figured it out from the technical side, most of the planned functionality works, then I have absolutely no experience with the start. I understand that it is very important to collect high-quality content, and the content is someone else's, it will be necessary to contact (calls, letters) with companies and tell why it will be fun, interesting and useful with us. In parallel, you will need to promote the site in search queries (SEO site). At launch, the site will be empty, with a small budget, I would like to spend as much as possible on advertising, unless of course it is needed, for this you need to correctly calculate the time.
Now I began to look for useful literature, articles to do everything right. So I decided to ask questions here, so to speak, on the shore before a big voyage.
- maybe someone will advise what to read on this topic, what you have already read and really found it useful
- maybe someone already has a similar experience, there is an opportunity to tell what problems they had, what they would do in the first place
- maybe it’s worth hiring a special one for these purposes human? But how to search? Who should he be? He must be on the RFP or agree to give away part of the pie, but at the same time he will take over everything. But recently I read that it is easy for such people to abandon the idea, since they did not invest anything financially, and when it seems to them that they are wasting their time, will they immediately leave?
- how to introduce ourselves correctly when we start contacting companies, whether it is necessary to immediately register a company / individual entrepreneur in order to immediately seem like a serious organization. I would like more chances for companies / clients to start trusting us;
I understand that the first pancake is lumpy and a bunch of startups close quickly, I would like to prepare as much as possible so that tomorrow I don’t think that I could prepare a little and do it differently. I think it will be useful to learn about other people's rake and just read smart and competent people in this area.
If I got in the wrong place with my question, then you can kick in the right direction. =)
Thanks in advance for your answers.

Answer 1

The questions are very vague, it all depends on the context of the project. The situation is typical if you raise the project for the first time.
You can hire me for consulting, help you estimate costs and highlight where to put more effort.

Answer 2

The fact is that in new versions of vue, in particular, in the second version, Evan You abandoned native filters, leaving only custom ones. As an alternative, he suggests using computed expressions. https://vuejs.org/v2/guide/migration.html#Filters

Answer 3

You need something like this `item in array | filterBy(input)` and then implement the filter itself. Although I can not check now whether it will work in this version. The common practice is to use a computed property that will contain the necessary elements and write it straight away like this: `item in filteredArray`.
