Hi @Leo T,
Google AdWords is a pay per click advertising solution where you set a maximum cost per click, a daily budget and start and stop dates. With that in mind, there is no way for anyone here to determine what AdWords would cost to promote you as you want. You would need to open an AdWords account, set it up, create campaigns, audit & optimize and maintain it.
You may want to spend some time learning more about Google AdWords.
