Digital FAW of a simple logo based on my sketch, for wordpress site - 17/03/2018 08:20 EDT

I have a clear idea of my private non-commercial wordpress site logo and sketched in on paper / in Powerpoint but don't have the means to make it a proper digital file. The logo consists of the two interwoven letters 'D' and 'G' and from far away should form a heart. I want a vector based file (Illustrator etc.) that I can keep and maybe further develop, have all IP rights and a graphic file optimized for wordpress/website logo in browsers or as avatar for posts, so very small. You should have experience with wordpress logos, one constraint is 'min. 512x512 pixel' and it should probably adaptable. I also want it to use it as a proper picture on the website, thus in a bigger resolution and against a dark grey background (RGB hex 3E-42-44 = dec 62,66,68 cf. pictures) and therefore the overall heart form should be surrounded by a white border. Ideally, it could be used against any background colour but if not possible, then pls. use 3E4244. The heart form should be harmonic and y-axis symmetric, so the pencil drawing provides you with the FORM OUTLINE, where you may play around a bit with the best proportions (I sketched it with a and a/3 but you may try out others such as a and a/4 etc.). The other photo built in Powerpoint is just for the colours and overall impression, NOT the about the exact form. I hope this is precise and descriptive enough for you! :) Thanks PS: I can't find where I upload my sketches, maybe in the next step or via email??
