Your gig needs a lot of work 
Video
It looks a bit cheap and unprofessional. Here’s what you can do
- In the video showcase your designs that you’ve created or the sites you’ve worked on.
- Hire proofreader to review your script
- Hire a voice over artist to read it over the video
If you do your homework then you can probably get it done under $100.
Your portfolio
If you don’t do full designs and only focus on CSS then add some case studies to your portfolio.
- Get a nice Word template with your branding
- Take some before / after photos to show what your service added
- Get some numbers if possible (revenue, traffic, user experience.) Whatever you’re allowed to use by the client.
- Hire a copywriter to write a decent description for the case study
- Upload it as PDF
I’m guessing the budget would be around $75-$100.
Last but not least, hire a proofreader for your gig description. ($20-$25 propably for just 1000 words)
