Need VERY simple code written for HTML Email

Email is 90% written I just can't figure out the last bit of table inside table and to clean my code (I'm a beginner). Must have experience with writing inline css and code for emails as it is very different from regular code. Needs to be compatible with ALL email clients. Needed ASAP. Need done within next 45min. Must have immaculate clean code. Should not take someone that knows what they are doing more than 30min to do.
