I need to increase web traffic

I'm looking for someone to do whatever is needed so that the following pages and corresponding keywords display on the first page of Google.

Here's the keywords and web pages.

Keyword - black hairstyles
Page - (https://universalsalons.com/category/hairstyles-gallery/blackhairstyles/)

Keyword - african american bob hairstyles
Page - (https://universalsalons.com/category/hairstyles-gallery/bob-hairstyles-gallery/)

Keyword - black braid hairstyle
Page - https://universalsalons.com/category/hairstyles-gallery/braids-hairstyles-gallery/

Firstly please let me know the TOTAL price (not monthly cost) of the project.

Secondly I have been let down by self-proclaimed 'SEO Professionals' in the past, therefore I need some form of guarantee whereby if you don't deliver on the results that you promise, within the time frame that you set, then the payment will not be due payable.

Please note that the quality of your guarantee will play a decisive factor in securing this role.

I look forward to hearing from you.
