tile setter

i have this white wall behind my toilet that i need to finish with more 2 by 2 gloss black tiles a small job but its the bottom that’s important, keeping everything in line and consistent with the grout lines on the right 4 sets of 24 by 24 tiles across around 50 square feet . the bottom would be a 2cm filler from the same tile i don’t want to baseboard it if you can do it if you have experience tell me how much you charge for this please send your contacts along with references.
