Design of a digital marketing strategy for a e-learning website

I am seeking an experienced digital marketing expert to create a high impact marketing campaign strategy for a new distance learning website. I need to understand what type of content, when to post it, how much of Google Ads should I use, what are the right social media channels, etc. I consider myself an entrepreneur and my resources are very limited for which I need the best value for money.

The main idea of the website is to sell 'self-paced technical courses' which content is specifically related to the electric power generation and transmission industry, but we are also offering a wide range of engineering services including field testing, reverse engineering, design review, troubleshooting, commissioning services, etc. therefore, in one way or another these services should also be presented.

The main focus of the marketing campaign should be to promote our products (Courses) and services, making emphasis that we are (or we will be) the first e-Learning platform fully dedicated to the electric power generation and transmission industry. The other objectives of the campaign should be to increase the awareness of our eLearning platform aiming to sending traffic back to our website.

I will need a quotation (preferably fixed fee), your introduction as expert on this field, timeframe to complete the project, and most important I would like to see verifiable successful experience in similar projects. I look forward for your proposal as I want to contract this project over the next 2-3 weeks, so please also confirm availability.
