We need professional sketches on the appropriate software to send to manufacturers

We are designing bikinis - we want you to make our sketches into reality. The first drawing we would like to test is a bandeau bikini, made out of 80% Polyamide, 20% Elastane. Our brand name is BLK LDN. The bikini will be black but we would like an elastic band in white underneath the black bandeau top with black writing repeating BLK LDN. the whole way round. Similarly on the bottoms (a black thong), we would like an elastic band on the top saying the same thing.
