Is He Being Honest? Javascript Upwork Proposal - Page Speed

Hello!
My background is weighed heavily in SEO/PPC, and after attempting a few botched "quick fixes" I've yet to see results.

Our page speed is around 2.5 seconds, for our server that is a bit slow. Previously were at around 1.1..long story short I've received a proposal on Upwork and was told this job would take 2-3 hours. Mainly just Javascript and HTML.

Does anyone have any input as to whether he is trying to get more money? Or if I am wayyy underestimating the mentioned task. Keep in mind the website is only around 5 pages and 1 blog post, all less than or around 1,000 words. We would also be doing all of the basic optimizations ourselves.

I've attached a screenshot of the results from PageSpeed Insights, thanks in advance to anyone that can help.

You need to provide more details as for now, you are not really making sense...

Dont really understand what you are saying, are you gonna pay someone to speed up your site?

If that is the case and you site is using wordpress, you can do all these things yourself and increase your site speed in 15 minutes. Follow some tutorials online, it is pretty basic stuff

Throw it all out - including your server. Replace everything. Theme too. No other option.

It used to be fast, and it's not fast anymore?? Did you make a change to cause that?

If it is Wordpress or some sort of MySQL driven website, I would first consider your Web Host. I worked for a huge shared web hosting company and this would happen all the time because we would get so many customers, and a lot of our database servers would get overloaded.

So... maybe if you have a friend on a dedicated server or something you could try uploading your DB (or whole site) there and updating your config file to connect there remotely and see if there are any differences.

Also, if you are using something like Wordpress, it has a lot of plugins you can install that help with speeding up the website. There's some that deal with caching, and probably some other ones.

As for the guy you're talking to... It's hard to really judge what exactly needs to be done without seeing your site. But from personal experience, Javascript can be a little complicated and take some time to work on. But on the other hand, I've never really seen websites that were slow due to Javascript stuff. It's usually always video/images/DB. Also, I don't know if I'd trust everything the report you ran says. Stuff like that you could run on any site, and it would have a ton of errors/fixes come up.
Anyways, you could try uploading some webpages on there that you know should work fast and see how it runs. Could also just be the http/apache server or whatever you want to call it

Good luck.
