need a theme developer

Hi there..
I am Osayomi Francis Oluwarotimi and i am contacting you in respect of a need.
I am trying to create a website as a project though, i did oracle recently and i want to upgarde to a level of web development and so i thought of trying a project that will be worth my effort at least at the long run.
I am from Ekiti State in Nigeria and the project i try to sort out is the state house of assembly website, though they are building theirs with help from the government but believe me if i can run through this project in time and if its worht it then you might just be my sent from heaven. In short, i want to know if i can get a customise theme that will look like and have the features of any of this two or the two combined i.e https://www.etisalat.com.ng and https://www.ekitistate.gov.ng but with particular reference to the ekitistate.gov.ng.
The theme will be compose of the colors red, green, and yellow with a green background and the header will have spaces for background pictures and two header images.I want a customise theme that i can edit to suit me with the help of plugins and please help me add the breadcrum navigational path, just make the theme look more like the ekitistate.gov.ng theme. You can add the neccessary creativity to the page template.
i just want to know if this is possible and what will it cost me personally?
If you can be my consultant and guide me through this project i will forever remain gratefull and to add to that i will use the project as a reference to a paying project in a state call Osun in Nigeria.
my wordpress username is [email protected] and thats my email too. WordPress is where i found you.
I will be waiting for your favourable reply
Thanks
Osayomi Francis O.
