I have developed custom websites (from scratch, and have worked with different themes as well).
I can provide following services:
1- Install WordPress on your domain, install theme, and do all the customization as per your requirements.
2- I have huge gallery of different themes, tell me niche of your website, I will send you few links to themes, select one of them, and we get started (THIS IS WHEN YOU HAVE NOT BOUGHT ANY THEME ALREADY), and theme I will provide will be totally free for you.
3- I will add the different necessary plugins for you.
4- Contact us form, and slider.
I also does offer services in Bootstrap based website which would be 100% responsive.
Please contact me before you place the order to discuss the requirements.
